Fig. 2 is the face the A-A cross-sectional view in Fig. 1.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
In this application unless specifically defined or limited otherwise, term " connection ", " fixation " shall be understood in a broad sense, example
Such as, it may be a fixed connection, may be a detachable connection, or is integral；It can be mechanical connection, be also possible to be electrically connected；
It can be directly connected, the connection inside two elements or two elements can also be can be indirectly connected through an intermediary
Interaction relationship.For the ordinary skill in the art, above-mentioned term can be understood at this as the case may be
Concrete meaning in invention.
In the description of the present application, it is to be understood that orientation or positional relationship indicated by term "front", "rear" is base
In orientation or positional relationship shown in the drawings, it is merely for convenience of description of the present invention and simplification of the description, rather than indication or suggestion
Signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this
The limitation of invention.
As shown in Figs. 1-2, the present invention provides a kind of purse-string forceps for single-hole laparoscopic surgery, including two pass through hinged shaft
30 hinged clamp handles 10 and two nail bins 20, the clamp handle 10 include the leading portion 11 and back segment for being located at 30 two sides of hinged shaft
12, the major part of the leading portion 11 of the preferably described clamp handle 10 is linear structure, and the length of the leading portion 11 of clamp handle 10 is longer, thus
So that the rear end of the leading portion 11 of clamp handle 10 is located at outside abdominal cavity during operation, one end of the nail bin 20 and a first rotating shaft 21 are fixed
Connection, the first rotating shaft 21 and the front end of the leading portion 11 of the clamp handle 10 are rotatablely connected, and the first rotating shaft 21 is by a setting
In 11 upper angle regulating mechanism 40 of the leading portion driving of the clamp handle 10, to drive the nail bin 20 to swing.By angular adjustment machine
After the adjusting of structure 40, nail bin 20 can be maintained on the position after any one swing.Angle adjusting mechanism 40 with hand adjustment section
Part be preferably provided at clamp handle 10 leading portion 11 rear end, so during operation be located at abdominal cavity outside, convenient for adjust.The present invention is logical
The mode that nail bin 20 and clamp handle 10 are arranged to rotation connection is crossed, thus intraperitoneal when needing for purse-string forceps to extend into through navel single hole
When, nail bin 20 is turned to it is substantially coplanar with clamp handle 10, when the front end of purse-string forceps extend into it is intraperitoneal and then by nail bin
20 turn to the angle substantially in 90 ° of clamp handle 10, thus realize purse-string forceps are used in single-hole laparoscopic surgery, Jin Erke
Mitigate the workload for carrying out suture Shi doctor in single-hole laparoscopic surgery, shortens operating time, improve the quality of purse string suture, subtract
Few operation risk.
As a further improvement of the foregoing solution, the angle adjusting mechanism 40 includes being separately positioned on the clamp handle 10
First pulley 41 and the second belt wheel 42 on the rear and front end of leading portion 11 and it is tightly placed in the first pulley 41 and described second
Transmission belt 44 on belt wheel 42.It is preferred that the transmission belt 44 is that synchronous belt is correspondingly set on first pulley 41 and the second belt wheel 42
There is a tooth engaged with synchronous belt, transmission in this way is accurate, and when work will not be slided.The first pulley 41 is sleeved on described first turn
On axis 21, one end of first rotating shaft 21 is fixedly connected with nail bin 20, the other end passes through 10 rear enclosure of clamp handle equipped with the first pulley
41, second belt wheel 42 is rotatablely connected by the leading portion 11 of the second shaft 43 and the clamp handle 10, second shaft 43 by
One locking device, which rotates it, to be locked, and preferably locking device is the spiral shell being arranged on the rear end of the leading portion 11 of the clamp handle 10
Nail 45, the screw 45 is threadedly coupled with clamp handle 10.Rotate first rotating shaft 21 by mobile transmission belt 44, to adjust nail bin
Angle between 20 and clamp handle 10 is regulated and then is locked by screw 45.Above-mentioned angle adjusting mechanism 40, structure
Simply, compact, it adjusts reliably, conveniently.
It as a further improvement of the foregoing solution, further include a synchronizing controls 50, the synchronizing controls 50 wrap
Include link block 51, two of the outside that two are separately fixed at two transmission belts 44 be separately fixed at two clamp handles 10 before
The guide ring 53 of the rear end of section 11 and both ends are each passed through the drawstring connecting after two guide rings 53 with two link blocks 51
52, the preferably outside that transmission belt 44 is fixed on by way of bonding of link block 51, the middle part of the hinged shaft 30 is provided with one and its
Coaxial through-hole 31, the diameter of hinged shaft 30 are oppositely arranged larger, and a tune being threadedly engaged with it is provided in the through-hole 31
Save bolt 54, the threaded shank for adjusting bolt 54 passes through the through-hole 31 and to be threadedly coupled with a sliding block 55, the sliding block 55 with connect
The same side that block 51, guide ring 53 and drawstring 52 are all located at hinged shaft 30 is connect, the sliding block 55 is slidably connected with a guide rod 56, described
A pilot hole 551 is provided on sliding block 55, the axis of the pilot hole 551 intersects with the axis of the hinged shaft 30, and drawstring 52 passes through
The pilot hole 551, the guide rod 56 are fixed in any clamp handle 10 and parallel with the adjusting bolt 54.Guide ring 53 is used
Drawstring 52 is oriented to so that the part between guide ring 53 and link block 51 of drawstring 52 with transmission belt 44 substantially
Keeping parallelism.Rotation adjusts bolt 54, then link block 51 is moved along the axis direction of hinged shaft 30, thus from the middle part band of drawstring 52
The both ends of dynamic drawstring 52 are mobile to same direction, and the moving distance at the both ends of drawstring 52 is consistent, and such two first turn
The swing angle of axis 21 is also consistent, and final realize is adjusted synchronously the angle of two nail bins 20, after adjusting, then distinguishes
Two nail bins 20 are kept on the position after adjusting by two screws 45.Drawstring in above-mentioned synchronizing controls 50
52 hinged shafts 30 for remaining constant due to have passed through position, regardless of two clamp handles 10 are swung around hinged shaft 30, drawstring
52 all will not because of clamp handle 10 swing and move, only can adjust bolt 54 adjusting under move, ensure that synchronous adjustment
Reliability.Synchronizing controls 50 in the present embodiment avoid when individually two nail bins 20 being adjusted, two nail bins 20
It is not easy to just, to influence sewing effect, increase the problems such as workload of doctor.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention, for this field skill
For art personnel, it is clear that invention is not limited to the details of the above exemplary embodiments, and without departing substantially from spirit of the invention or
