Description

Drag hook for endoscopic thyroid surgery

Technical Field

The utility model relates to a clinical surgical instruments technical field especially relates to an endoscope drag hook for thyroid surgery.

Background

At present, the endoscopic thyroid surgery is more and more accepted by patients due to the advantages of no neck scars after the surgery and the like. When the endoscope is used for the thyroid operation, the operation visual field is more specific by using the draw hook under the endoscope operation, and the draw hook plays a role in protecting blood vessels, nerves, muscles and the like. The endoscope retractor which is used clinically at present is shown in figure 1, and comprises a handheld part 1, a transition part 2 and a hook part 3, wherein the transition part 2 and the hook part 3 are generally integrally formed, and a sharp head part 31 of the hook part is generally relatively sharp, and the sharp head part 31 has the advantage that the endoscope retractor can easily penetrate through skin to reach an operation visual field and play a role. However, it also has significant disadvantages: the problems of blood vessel puncture by the sharp head 31, bleeding caused by muscle and the like inevitably occur in the drawing process, even serious medical accidents can be caused, and poor experience and pain are brought to medical staff and patients.

In order to solve the above problems, the prior art reports some improved schemes, such as chinese utility model patent with application number 202022016518.8, which discloses an endoscopic thyroid retractor capable of avoiding damage by a puncture needle, however, the retractor has the following disadvantages: 1. the drag hook has a complex structure, is difficult to process, has high manufacturing cost and is not suitable for practical application; 2. when the draw hook is used, the operation is complex and inconvenient, and the operation efficiency is low.

Disclosure of Invention

An object of the utility model is to provide a drag hook for endoscopic thyroid surgery to solve the above problems.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides an endoscope drag hook for thyroid surgery, includes handheld portion, transition portion and crotch portion, still includes the nook closing member be provided with on the crotch portion and be used for nook closing member male opening, the anterior segment of crotch portion is provided with and is used for holding the well kenozooecium of nook closing member, the head of crotch portion link up and be dull form head.

The utility model discloses set up the anterior segment of drag hook into cavity form and set up the head into blunt form to the independent setting can conveniently insert and take out the nook closing member of drag hook anterior segment, be about to nook closing member and drag hook anterior segment and set up to the sleeve structure, conveniently pierce the skin with the drag hook after, take out the nook closing member, thereby avoided the emergence that sharp-pointed head punctures blood vessel, musculature etc.

As a preferred technical scheme: the blunt head is smooth. The smooth head further improves the safety of the operation.

As a preferred technical scheme: the tail end of the stylet is provided with a handle. The insertion and the extraction of the needle core can be convenient. The outer diameter of the handle part is larger than the front needle core main body, and is also larger than the inner diameter of the opening part, so that the handle and the opening part have certain engagement degree, the needle core and the hollow part are not fallen before reaching the operation visual field, and the needle core and the hollow part are convenient to take out after reaching the operation visual field.

As a preferable technical scheme: the position of the needle core, which is 1.5-5mm away from the needle point, is in interference fit with the inner side of the blunt head. That is to say, the position of certain distance apart from the needle point of nook closing member, with blunt form head joint, can be that blunt form head has certain elasticity and realizes, can prevent like this that the nook closing member from inserting well kenozooecium too deeply and difficult taking out, also can prevent that the nook closing member from inserting well kenozooecium too deeply and causing the potential safety hazard of operation, and, can also prevent that the needle point from pricking in-process nook closing member because hollow part does not have the resistance and can't pierce, pierce the back, remove the interference fit of nook closing member and well kenozooecium through drawing the nook closing member, thereby take out the nook closing member.

The hollow part is too deep: the periphery of the handheld part is provided with anti-skid convex lines. Can improve the stability of the whole draw hook.

Compared with the prior art, the utility model has the advantages of: the utility model discloses a telescopic structure compromises the retractor nook closing member sharpness simultaneously and punctures skin muscle and reachs the operation art wild, avoids the sharp injury of unnecessary again, plays the due effect of retractor, has greatly improved laparoscopic surgery's security and patient's satisfaction, moreover, the utility model discloses a retractor, simple structure makes easily, and is with low costs to convenient operation, operating efficiency is high.
