Abstract

The utility model discloses a spine side path minimally invasive surgery channel device used for a spine side path minimally invasive surgery. The spine side path minimally invasive surgery channel device comprises a working sleeve. Blocking pieces and an inner layer sleeve are arranged in the working sleeve, an annular opening is formed in the top of the working sleeve and further provided with a fixing hole and a fixing arm, the upper end of each blocking piece is arranged on the top of the working sleeve, the lower end of each blocking piece stretches out of the working sleeve, and the lower end of each blocking piece is bent outwards. The inner layer sleeve comprises a cylinder top, and a cylinder clamp is clamped in the inner wall of the working sleeve. The blocking pieces and the inner layer sleeve which can be assembled and the dismountable fixing arm are arranged in the working sleeve, and the bottom ends of the blocking pieces are fixed in muscular tissue, so the fixing effect of the spine side path minimally invasive surgery channel device in a target surgery area is good, the muscular tissue can be propped up through compaction and fixation by the pair of the blocking pieces, and the fixing mode of the working sleeve is flexible because of the fixing hole in the top end of the working sleeve.

Description

A kind of spinal column dypass Minimally Invasive Surgery lane device

Technical field

This utility model relates to a kind of operation path device, especially a kind of spinal column dypass Minimally Invasive Surgery lane device.

Background technology

in Minimally Invasive Surgery, the general employing of operative region inserted sleeve as the lane device that struts operative region, after yet general sleeve is inserted, because being the cylindricality bottom, sleeve integral body there is no fixture effectively, make the sleeve of inserting after muscular tissue, under the internal stress of soft tissue and muscular tissue outside operative region bias internal, be unfavorable for that the medical worker operates operative region, and because the bottom of sleeve is generally flat mouth, also to need to carry out muscular tissue often helpless while strutting when the target operative region, the fixed mechanism operated by rotary motion of sleeve is on the both sides at the top of sleeve, when sleeve needs the conversion implantation mode, the apparatus of fixed muffle also need move.

The utility model content

For the problems referred to above, this utility model provides a kind of operative region good fixing effect, can carry out after inserting sleeve that muscular tissue struts, sleeve fixed form spinal column dypass Minimally Invasive Surgery lane device flexibly.

Technical problem to be solved in the utility model is achieved through the following technical solutions:

A kind of spinal column dypass Minimally Invasive Surgery lane device, comprise the work sleeve, is provided with catch and inner layer sleeve in described work sleeve, and described work sleeve top is provided with ring port, also is provided with fixing hole on described ring port, and described ring port is provided with fixed arm.

Work sleeve top is located in end, described catch upper end, and the work sleeve is stretched out in described catch lower end, end, described catch lower end outward.

Described catch length is greater than the work length sleeve, and end, described catch upper end is provided with hole.

Described inner layer sleeve comprises the handle of end, upper end, the collet chuck of lower end and the linking arm between handle and collet chuck, and described handle is located at work sleeve top, and described collet chuck is pressed on the work sleeve lining.

Described inner layer sleeve length is not more than the work length sleeve, and described handle is provided with fixing hole.

Also be provided with groove in described work sleeve, described inner layer sleeve groove shapes is corresponding with linking arm.

Described fixed arm one end is fixed on ring port, and the described fixed arm other end is provided with the opening cutting ferrule.

The beneficial effects of the utility model are:

This utility model can be by arranging assemblnig catch, inner layer sleeve and dismountable fixed arm in the work sleeve, the catch bottom is fixed in muscular tissue and makes this lane device good fixing effect in the target operative region, the a pair of catch that is fixed can carry out after inserting sleeve that muscular tissue struts, a plurality of fixing holes on sleeve top make the fixed form of work sleeve flexible, needn't the moving sleeve fixed apparatus.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

Fig. 1 is this utility model overall structure schematic diagram;

Fig. 2 is this utility model inner layer sleeve structural representation.

In figure, 1. work sleeve, 2. catch, 3. inner layer sleeve, 4. fixed arm, 5. handle.

The specific embodiment

This spinal column dypass Minimally Invasive Surgery lane device agent structure consists of work sleeve 1, catch 2, inner layer sleeve 3 and fixed arm 4.

As shown in Figure 1, the top of work sleeve 1 is the evagination port of annular, offers uniformly fixing hole on ring port, and fixing hole is used for being mounted with the handle 5 of arm 4 and inner layer sleeve 3, and on ring port, correspondence position is installed fixed arm 4.

Catch 2 is preferably two, in the work that the is arranged on sleeve 1 of catch 2 symmetries, be affiliated at work sleeve 1 top catch 2 ends, upper end, catch 2 ends, upper end offer hole, and this hole is used for connecting surgical instrument, better to strut the muscular tissue of work sleeve 1 below, catch 2 length should be greater than work sleeve 1 length, make catch 2 lower ends can stretch out work sleeve 1 lower end, catch 2 end, lower end outwards, make catch 2 lower ends better be fixed in muscular tissue.

Inner layer sleeve 3 comprises the handle 5 of end, upper end, the collet chuck of lower end and the linking arm between handle 5 and collet chuck, inner layer sleeve 3 length are not more than work sleeve 1 length, offer fixing hole on handle 5, handle 5 can be fixed by screws in work sleeve 1 top, and collet chuck is pressed on work sleeve 1 inwall.

Work sleeve 1 inwall also is provided with groove, and the inner layer sleeve groove shapes is corresponding with linking arm, and groove location is corresponding with fixing hole.

Fixed arm 4 one ends are fixed by screws on fixing hole on ring port, fixed arm 4 other ends are provided with the opening cutting ferrule, the opening cutting ferrule can be fixed on armarium easily, while needing adjusting work sleeve orientation, direct adjustment screw, make fixed arm 4 unclamp, and then fixed arm 4 is fixed and got final product.

Should be understood that, the above-mentioned specific embodiment of the present utility model only is used for exemplary illustration or explains principle of the present utility model, and does not form restriction of the present utility model.Therefore, in the situation that do not depart from any modification that spirit and scope of the present utility model make, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.In addition, this utility model claims are intended to contain whole variations and the modification in the equivalents that falls into claims scope and border or this scope and border.
