Abstract

Disclosed is an operative pull hook which is conducive to reducing incision length, incision healing and various intraoperative observation operations. A main hook (1) is arranged at one end of a hook body, an auxiliary hook (4) is arranged at the other end of the hook body, a through groove (3) is formed in the middle of the hook body, length of the main hook is 65-120 mm, and a smoke guide tube (2) is adhered in an area, extending to a hook back, of the outer side of the main hook. One end, facing the tail end of the main hook, of the smoke guide tube is provided with an opening, and one end, facing the hook back, of the smoke guide tube is provided with an opening and is away from a plane, in which the hook bottom is positioned. The operative pull hook is suitable for being used to build an operative working cavity.

Description

A kind of surgery tractor

Technical field

The present invention relates to operating theater instruments, chamber drag hook is built in particularly operation.

Background technology

The sickness rate of thyroid carcinoma becomes ascendant trend year by year at present, the progress checked along with CT, ultrasonic etc., preoperative planning pair The assessment of disease is the most perfect, and the detection of contralateral seventh cervical regional lymph node metastasis is more sensitive, and even pharynx side etc. previously think rare The lymphatic metastasis at position also can more early find, the enforcement of corresponding side neck lymph dissection operation the most constantly improves.

In terms of operative incision approach, most medical institutions can substitute tradition L with lower cervical region decolletage formula otch Type otch completes the associative operation of side neck lymph dissection, makes incision size greatly reduce, but brought is upper neck simultaneously Region, portion, as not good enough in the exposure in II district and working place is narrow and small and is difficult to the operation problems such as effective maintenance.

Stable and the adjusting means of endoscope operation cavity disclosed in CN1883400A, is particularly suitable for Thyreoidine scope Operation, this device is used for setting up internal operation cavity (working-space), and stability is high, and cavity space is easy to adjust, Operation is conducive to be smoothed out.But its structure of surgery tractor being equipped with due to this device is single with size, it is difficult to solve above-mentioned difficulty Topic；Next to that the smog that field of operation tissue produces through high temperature apparatus effects such as electric knifes is difficult to get rid of, greatly reduce operation vision area Definition, impact operation is normally smoothed out；Owe rationally, to be unfavorable for the neck sheath being pulled, muscle because of hook end structure besides Protection in tissue.

Summary of the invention

The invention solves the problems that the surgery tractor setting up operation cavity in prior art can not meet operation on neck, especially It is the needs of the deep working place of incision in neck operation acquisition, and field of operation produces smog and is difficult to get rid of, and affects in art and executes The person of controlling, to problems such as every observation operation are carried out, provides a kind of surgery tractor of the present invention for this, and this surgery tractor is suitable for Incision in neck and obtain the needs of deep working place, can get rid of field of operation produce smog, be conducive to led neck sheath and flesh The protection of meat.

For solving the problems referred to above, the technical solution used in the present invention is to have main hook in coupler body one end, and the coupler body other end has Having auxiliary hook, have groove in the middle part of coupler body, it is characterized in that its a length of 65 120mm of described main hook, extends to outside main hook Back one region is attached with draws smoke pipe, and this draws smoke pipe towards main hook end direction one end open, draws smoke pipe towards back direction one End opening and this end leave plane residing for back.

Draw smoke pipe and leave plane residing for back towards one end, back direction, be that drawing smoke pipe invests district of back segment proximal portion Section excurvation leaves plane residing for back.

Drawing smoke pipe and leave plane residing for back towards back direction one end open and this end, this end passes through connecting leg external connecting negative pressure (low pressure) system, can attract to discharge by the smog that field of operation produces.

Preferably:

The described smoke pipe that draws is connected with pipe joint towards one end, back direction.

Described main hook end is arc.

Due to the fact that a length of 65 120mm of main hook, especially 90 120mm's, operation on neck coordinates WSM-I Type is built chamber device and is used, and can provide the support as deep as upper neck region from lower cervical incision, it is provided that the work chamber of lasting stability, It is thus possible to tradition L-type otch to be changed into lower cervical region decolletage formula otch, it is substantially reduced incision length, beneficially wound healing, moreover it is possible to disappear Except patient because of cervical region leave that scar brings unhappy；Again owing to extending to the attachment of back one region outside main hook of the present invention Have and draw smoke pipe, therefore can attract to discharge by the smog that field of operation produces, be conducive to every carrying out observing operation in the person's for the treatment of art；Again Be exactly main hook end be arc, it is simple to the tractive of the organizational structuries such as neck sheath, muscle is unlikely to damage these tissues by art.

Detailed description of the invention

A kind of surgery tractor, coupler body one end has main hook 1, and the coupler body other end has auxiliary hook 4, has groove 3 in the middle part of coupler body, Its a length of 120mm of main hook 1, extends to back one region and is attached with and draws smoke pipe 2 outside main hook 1, this draws smoke pipe towards main hook end Extreme direction one end open, draws smoke pipe and leaves plane residing for back towards back direction one end open and this end, draw smoke pipe towards hook Back of the body one end, direction is connected with pipe joint 5；Main hook 1 end 11 is arc.

Another embodiment is a length of 65mm of main hook, and other structures are same as described above.

Another embodiment is a length of 95mm of main hook, and other structures are same as described above.
