Description

Incision expander with smoke exhaust hole

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to take incision expander of exhaust hole.

Background

The endoscopic surgery in the minimally invasive surgery can be completed by only one incision, along with the development of the endoscopic surgery technology, surgical medical equipment such as an electrocoagulation hook, an electrotome, an ultrasonic scalpel and the like also develops rapidly, the equipment cuts tissues by high-frequency current or ultrasonic waves, and the high-energy surgical equipment can generate certain smoke on the cut tissues due to high frequency and high energy, so that the definition of an endoscopic lens is seriously influenced, and the surgical effect of a doctor is directly influenced. Generally, the smoke generated during the operation is sucked out by using a smoke sucking device, however, the smoke sucking port of the smoke sucking device must be deeply penetrated into the operation site through the wound, so that the operation process is interrupted, the operation process is delayed, and the operation effect is possibly reduced.

The utility model discloses an authorized bulletin number CN208193128U relates to a medical instrument, especially an incision expander. It includes: the incision expander part consists of an outer snap ring, an inner snap ring and a channel for connecting the inner snap ring and the outer snap ring, and the fixer part consists of a stretching belt, a fixing clamping seat, a lens fixer and a smoke suction pipe preformed hole on the lens fixer. The utility model provides a take incision expander of exhaust hole, it can realize the simplification of operation smog suction process, does not need to carry out the smog suction operation alone at the operation in-process, has simplified the operation process for the operation process.

However, the above utility model still has the disadvantages: after the smoke suction pipe is inserted into the smoke suction pipe reserved hole on the lens fixer, in the smoking process, due to improper operation of an operator, the smoke suction pipe can be folded at the inlet and outlet holes at the upper end and the lower end of the smoke suction pipe reserved hole to form fold marks, smoke can not flow smoothly at the fold marks, the smoking process efficiency is reduced, the operation process is further delayed, and even the operation effect can be reduced.

SUMMERY OF THE UTILITY MODEL

The incision expander comprises a smoke suction pipe, a smoke exhaust pipe.

The utility model discloses a realize through following technical scheme: the utility model provides a take incision expander of exhaust port, includes incision expander body and runs through the smoking pipe preformed hole of establishing on the lens fixer of incision expander body, the downthehole upper and lower end of smoking pipe preformed hole is equipped with elastic buffer portion, elastic buffer portion includes outer loop, inner ring and elastic contraction area, the outer loop is fixed to be established on the inside wall of smoking pipe preformed hole, the rigid coupling has the elastic contraction area between outer loop and the inner ring.

The elastic contraction band comprises elastic supporting pieces and a contraction band, and the elastic supporting pieces are uniformly distributed in the contraction band at intervals along the circumference.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses upper and lower end is equipped with elastic buffer portion in the smoking pipe preformed hole, the smoking pipe passes elastic buffer portion, oppress elastic buffer portion when the business turn over department of smoking pipe preformed hole takes place to fold when the smoking pipe, elastic buffer portion can be fallen the power buffering that the smoking pipe oppression produced, and then prevent that the business turn over hole department of smoking pipe and smoking pipe preformed hole from taking place rigid fold, guarantee the smooth and easy of smoking process, improve the efficiency of smoking process, and then accelerate the process of operation.

FIG. 2 is an enlarged view at A in FIG. 1;

fig. 3 is a schematic front view of the present invention;

fig. 4 is an enlarged view at C in fig. 3.

In the drawings: 1. an incision dilator body; 2. a lens holder; 3. a smoke suction pipe is reserved with a hole; 4. an elastic buffer part; 41. an outer ring; 42. an inner ring; 43. an elastic shrink band; 431. an elastic support member; 432. a shrink band.

Detailed Description

The incision expander with the smoke exhaust hole as shown in fig. 1 to 4 in the attached drawings of the specification comprises an incision expander body 1 and a smoke tube preformed hole 3 penetrating through a lens holder 2 of the incision expander body 1, wherein an elastic buffer part 4 is arranged at the upper end and the lower end in the smoke tube preformed hole 3, the elastic buffer part 4 comprises an outer ring 41, an inner ring 42 and an elastic contraction band 43, the outer ring 41 is fixedly arranged on the inner side wall of the smoke tube preformed hole 3, and the elastic contraction band 43 is fixedly connected between the outer ring 41 and the inner ring 42.

The elastic band 43 comprises an elastic support 431 and a band 432, the elastic support 431 is circumferentially and evenly distributed in the band 432 at intervals, when the smoking pipe presses the elastic buffer 4, the elastic support 431 contracts to drive the band 432 to contract, and the force generated by pressing the smoking pipe is buffered by the elastic force of the elastic support 431.

The utility model discloses upper and lower end is equipped with elastic buffer portion in the smoking pipe preformed hole, the smoking pipe passes elastic buffer portion, oppress elastic buffer portion when the business turn over department of smoking pipe preformed hole takes place to fold when the smoking pipe, elastic buffer portion can be fallen the power buffering that the smoking pipe oppression produced, and then prevent that the business turn over hole department of smoking pipe and smoking pipe preformed hole from taking place rigid fold, guarantee the smooth and easy of smoking process, improve the efficiency of smoking process, and then accelerate the process of operation.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
