technical field

The utility model relates to the technical field of medical equipment, in particular to a puncture needle positioning mechanism guided by ultrasound in a thoracic surgery ICU.

Background technique

Ultrasound probes are mainly used for ultrasonic diagnosis, such as B-ultrasound, ultrasonic physiotherapy, etc. The current ultrasonic probes are all ultrasonic transducers that directly act on the human body. When using, a layer of couplant must be applied to the skin to reduce ultrasonic conduction. resistance.

Existing thoracic surgery faces more clinical factors and needs to deal with more problems, which requires a full clinical understanding of the patient's physical symptoms in order to formulate corresponding emergency plans in advance. Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity. A puncture needle is a common tool used in the puncture process, especially in some inspection items, which need to be checked by a puncture needle. However, it is difficult to control the specific position during the inspection process, especially in the ultrasound-guided inspection of thoracic surgery, the way the stent is adjusted is too rigid, which will damage normal tissue, and the general medical staff still controls the puncture needle by direct manual control. It is difficult to accurately determine the location of the lesion on the level of ultrasound guidance, and the structure of automatic puncture needle positioning is too complex and inconvenient for flexible operation.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in FIGS. 1 to 3 , the present invention provides a puncture needle positioning mechanism guided by ultrasound in a thoracic surgery ICU, comprising a fixed sleeve bracket 1 , and a lead screw 3 is arranged in the hollow cavity of the fixed sleeve bracket 1 , And a lead screw nut 2 mounted on the lead screw 3 is sleeved in the hollow cavity, a knob 4 is fixedly installed on the top of the lead screw 3, and a connecting column 7 is fixed on the lead screw nut 2 , and the other end of the connecting column 7 is fixed on the protractor 6 .

A movable groove 5 is provided on one side of the fixed sleeve bracket 1 , the connecting column 7 passes through the movable groove 5 and moves along the movable groove 5 , and a collar 8 is provided at the center of the protractor 6 . A puncture needle cover seat 9 is rotatably mounted on the ring 8 , and a movable knob 10 is provided on the puncture needle cover seat 9 .

It should be added that the other end of the fixing sleeve bracket 1 is provided with an installation through hole 11 , and the other end of the installation through hole 11 is composed of two sets of clips 12 , and between the two sets of clips 12 Connected by movable bolts 13.

The fixed sleeve bracket 1 is provided with two sliding grooves 14 , both of which are provided with self-tapping knobs 15 that can slide along the sliding grooves 14 , and the opposite side of the self-tapping knobs 15 A splint 16 corresponding to the groove on the ultrasonic probe is fixedly installed on both of them.

As a preferred embodiment, the ultrasonic probe is inserted into the installation through hole 11 of the fixed sleeve bracket 1 , and the clip is fastened by the movable bolt 13 for the first fixing, and then the ultrasonic probe is first fixed by the clip 16 . Secondary fixation.

After the ultrasonic probe is fixed, the patient's lesion position is detected by the ultrasonic probe. After the lesion position is determined, the puncture needle is placed on the puncture needle sleeve holder 9, and the puncture needle is moved to the skin above the patient's diseased position. Use the knob 4 to wire To adjust the left and right positions of the screw nut, turn the knob 4 to drive the screw nut 2 on the screw 3 to move, and the rear screw nut 2 drives the connecting column 7 and the collar 8 to move to achieve the purpose of moving the puncture needle, and then cooperate with the ultrasonic display The angle of the threading needle is reasonably controlled for the lesion location.
