Problems solved by technology

This utility model mainly expands the vertical operation space, and cannot form the bottom horizontal space. Its operation flexibility and positioning accuracy are not as good as artificial retractors. When the gland is large, there is no expansion of the operation space on the opposite side, and it is difficult to obtain satisfactory results. operation field; at the same time, the retractor is only suitable for laparoscopic-assisted small incision surgery, not for complete laparoscopic surgery

Embodiment 1

[0033] Such as Figure 1 ~ Figure 3 Shown is a fitting type draw hook with a telescopic locking function, including a main draw hook and an auxiliary draw hook. The front end of the main draw hook is the main draw hook body 11, the middle is the main draw hook rod 12, and the tail is the main draw hook handle 13. The front end of the auxiliary drag hook is an auxiliary drag hook body 21, the middle is an auxiliary drag hook rod 22, and the tail is an auxiliary drag hook handle 23, wherein:

[0034] The main drag hook rod 12 is a hollow tubular structure axially penetrating with a through hole;

[0035] The auxiliary hook rod 22 passes through the main hook rod 12, and the auxiliary hook body 21 and the auxiliary hook handle 23 of the auxiliary hook extend out of the two sides of the through hole of the main hook rod 12 respectively;

[0036]The main retractor body 11 and the auxiliary retractor body 21 are mirror-symmetric structures, and the main retractor body 11 and the au...

Embodiment 2

[0045] A fit-type draw hook with telescopic locking function, the first arc handle 132 and the second arc handle 133 are respectively arc structures, and the opening direction thereof faces the main draw hook rod 12 . The first arc-shaped handle 132 and the second arc-shaped handle 133 are more in line with the curvature of the fingers, which is convenient for rotating the hook and adjusting the pulling posture.

[0046] Preferably, the main retractor body 11 and the auxiliary retractor body 21 are respectively "U"-shaped structures, and the main retractor body 11 and the auxiliary retractor body 21 form a bent oblong structure after fitting. After the main hook body 11 and the auxiliary hook body 21 of the "U" shape structure enter the operation cavity, they have a certain orientation during the rotation process, which facilitates the adjustment of the spatial position, and the rest are the same as in the first embodiment.

Abstract

The invention relates to the technical field of medical instruments, in particular to a fit type wire retractor with a telescopic locking function during an operation. The fit type wire retractor comprises a main wire retractor and an auxiliary wire retractor, a main wire retractor body is arranged at the front end of the main wire retractor, a main wire retractor rod is arranged in the middle of the main wire retractor, a main wire retractor handle is arranged at the tail of the main wire retractor, an auxiliary wire retractor body is arranged at the front end of the auxiliary wire retractor, an auxiliary wire retractor rod is arranged in the middle of the auxiliary wire retractor, and an auxiliary wire retractor handle is arranged at the tail of the auxiliary wire retractor. The fit type wire retractor has the advantages that the fit type main wire retractor and auxiliary wire retractor can be fit or separated, and the aim of pulling surrounding tissue and fully expanding operating space to expose the operating view field of the operation is achieved; under the cooperation of the locking function, the defect that an assistant can only expose the operation field by holding two retractors for continuous pulling with the two hands during the operation can be effectively overcome. The composite wire retractor is simple in structure, convenient to use and flexible to operate, the exposure range of the operation field can be adjusted effectively, the situation that during the operation, inconvenience is caused by opposite pulling of the assistant, and fatigue is caused by long-time pulling is reduced, and the operating space of the operation is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fitting-type draw hook with telescoping and locking functions for intraoperative use. Background technique [0002] The advantage of endoscopic surgery is that it can provide the surgeon with a clearer and finer anatomical representation and tissue space than under open direct vision under a magnified field of view. However, it has a narrow operating space, limited means of exposing the surgical field and controlling bleeding Defects such as the obvious weakening of the operator's "tactile" function will also bring more risks to the patient. [0003] Taking endoscopic thyroidectomy as an example, the thyroid gland is a trachea with rich blood supply and is prone to bleeding, often due to improper treatment of the superior and inferior thyroid arteries or middle veins, rupture of solid tumors, hemorrhage from enlarged blood vessels in the gland section, and accidental in...
