Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a surgical retractor for use in endoscopic thyroid surgery.
Background
In recent years, endoscopic thyroid surgery has been fully applied to clinical practice at home and abroad due to the advantages of small and hidden incision, no incision scar on the neck after operation and the like. In the conventional open thyroid surgery, it is very important that the surgical field is clearly exposed, so that the anterior cervical muscle group in front of the thyroid gland must be pulled away by using a retractor in the surgery, but in the endoscopic surgery, the conventional surgical retractor is too large to be used. If the anterior cervical muscle group is pulled by using the endoscopic forceps, more endoscopic surgical incisions are required to be added, and in the operation process, the instrument can shield part of the endoscopic vision, so that the operation of an operator is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a surgical retractor for use in endoscopic thyroid surgery, which is not enough to the prior art and has simple structure and convenient popularization.
A surgical retractor for endoscopic thyroid surgery comprises a connecting rod, a retractor head and a handle, wherein the connecting rod is of a hollow structure, an internal thread is arranged at the bottom end of the connecting rod, an air duct communicated with the inside of the connecting rod is arranged at the top end of the connecting rod, an external thread is arranged on the retractor head, the retractor head is connected to the bottom of the connecting rod through the thread, and a suction hole is formed in the retractor head; the handle is arranged at the top of the connecting rod.
Preferably, the suction hole is provided in plurality.
Preferably, the hook head comprises a hook body and a hook head which are hinged with each other, the hook body is connected to the bottom of the connecting rod through threads, and the suction hole is formed in the hook head; the pull rope is arranged inside the connecting rod, one end of the pull rope is fixed at the suction hole, the other end of the pull rope extends out of the air guide tube, and the pull rope is used for controlling the bending angle of the hook head.
Preferably, the outer surface of the handle is provided with anti-skid convex points.
The utility model has the advantages that:
the utility model discloses convenient operation, the operation in-process tractive thyroid gland focus tissue on every side of being convenient for, furthest's expansion operation field of vision has characteristics such as operation flexibility and safety in utilization.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention easier to be clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
As shown in the attached drawings, the surgical retractor for endoscopic thyroid surgery comprises a connecting rod 1, a retractor head 2 and a handle 3, wherein the connecting rod 1 is of a hollow structure, internal threads are arranged at the bottom end of the connecting rod 1, an air duct 4 communicated with the interior of the connecting rod 1 is arranged at the top end of the connecting rod 1, external threads are arranged on the retractor head 2, the retractor head 2 is connected to the bottom of the connecting rod 1 through threads, and a plurality of suction holes 5 are formed in the retractor head 2; the handle 3 is arranged at the top of the connecting rod 1. The outer surface of the handle 3 is provided with anti-skid convex points.
During the operation, in sending the clearance of being operated person's neck front subcutaneous operating space to with draw hook head 2 through stabbing for mirror chamber apparatus such as cartoon separation pincers, its connecting rod 1 then pierces through skin outside the neck skin from the extroversion to the inside, also gets into neck front subcutaneous operating space, at neck front subcutaneous operating space, with the head and the first 2 threaded connection of draw hook of connecting rod 1, through rotating connecting rod 1 and draw hook head 2, make both fix together through the screw combination, put the draw hook head beside the thyroid gland tumour that needs are retracted. An operator pulls the handle 3 and the connecting rod 1 in vitro, adjusts the position, the direction and the strength, and pulls open the thyroid tumor, so that the thyroid lesion can be exposed. When the operation is finished, the head and the rod which are fixed together through the thread combination are separated by reversely rotating the connecting rod 1 or the drag hook head 2, the connecting rod is directly extracted through skin, and the drag hook head 2 is taken out of the body from the subcutaneous operation space in the front of the neck by poking and clamping cavity mirror instruments such as separating forceps and the like.
The draw hook head 2 is provided with the suction hole 5 which can suck away the smoke generated by the ultrasonic knife and discharge the smoke through the air duct, thereby effectively ensuring the clear visual field when the focus part is cut by the ultrasonic knife and avoiding the skin injury caused by the ultrasonic knife.
In another embodiment of the utility model, the drag hook head 2 comprises a hook body 21 and a hook head 22 which are hinged with each other, the hook body 21 is connected to the bottom of the connecting rod 1 through screw threads, and the suction hole 5 is positioned on the hook head 22; the inside of connecting rod 1 is equipped with the stay cord, and the one end of stay cord is fixed in attracts hole 5 department, and the other end extends air duct 4, and the stay cord is used for controlling the angle of buckling of gib head 22. Thus, the angle of the hook head can be controlled by the pulling rope, and the hinged part of the hook body 21 and the hook head 22 rebounds after the pulling rope is sent.
The utility model discloses convenient operation, the operation in-process tractive thyroid gland focus tissue on every side of being convenient for, furthest's expansion operation field of vision has characteristics such as operation flexibility and safety in utilization.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
