Abstract

The utility model belongs to a medical instrument, used for the strong traction to an abdominal wall during operations of hepatectomy, splenectomy, etc. The utility model can replace manual traction, lightens the labor intensity of a doctor, and has continuous and uniform traction force. The traction strength and traction angle can be freely adjusted. The utility model is composed of a stand body 1, a capstan 2, a traction rope 3, a draw hook 4, and a traction hook 5. The utility model is characterized in that a clutch is arranged in the capstan, the clutch is a tooth end clutch, the traction hook 5 is of a plate type, the hook end of the traction hook is provided with a row tooth-shaped claws, and the slippage of a traction body can be prevented.

Description

Powerful mechanical traction hook

Belong to medical apparatus and instruments, be specifically related to a kind of surgery instrument.

Current, when hospital makes lobectomy of liver, hemihepatectomy, splenectomy and pancreatectomy at home, liver sausage coincide and cardia is performed the operation, in order fully to expose the art open country and to be convenient to operation, need manually to draw with hands, if operating time is longer, manpower is difficult to adhere to, is easy to generate tired or at times strong and at other times weak phenomenon, and the influence operation is carried out.

The purpose of this utility model is to provide a kind of apparatus to replace artificial traction, and its pull strength continues evenly, and the size of dynamics and the angle of traction can be adjusted.

The technical solution of the utility model is provided by Fig. 1, it is made of column 1, capstan winch 2, pull rope 3, drag hook 4, hook 5, its central post 1 is fixed on the operation table, capstan winch 2 can be adjusted up and down to adapt to the needs of traction angle along column, in addition, several towing pads are arranged on the hook, and drag hook is pulled in each Kong Shangjun can make hook adapt to the needs of different angles.A clutch is arranged in the capstan winch 2, clutch closed and throwing off can realize pull rope 3 and hook 5 be in mention, stop, relaxation state.Hook 5 is board-like, and there is a toothrow shape pawl at the tip of hook, can prevent to be pulled the body slippage.Characteristics of the present utility model are: realized drawing with apparatus in the operation, its pull strength is lasting, even, according to exposing the wild needs of art, can adjust traction dynamics and angle at any time, has alleviated patient and assistant's labor intensity greatly.

Below in conjunction with embodiment this utility model is elaborated:

Fig. 2 is the sketch map of hook 5, and its shape such as palm four refer to collude song, and its front end has four towing pads.

Fig. 3 be the K of hook to diagrammatic sketch, its hook end has a toothrow shape pawl.

Fig. 4 is the sketch map of capstan winch.

Fig. 5 is the vertical view of Fig. 4.

Capstan winch is made of clutch 6, cam 7, reel 8, handle 9, spring 10, lead 11, camshaft 12, and feature is that clutch 6 is increment clutches.

Operation principle is: pull rope 3-end is fixed on the reel 8, and the other end is fixed on the drag hook 4, and according to the angle needs, drag hook can be pulled in any one towing pad of hook; Rotating cam axle 12 makes cam 7 that clutch 6 disengaging (as Fig. 4, position shown in Figure 5) reels 8 are in relaxation state, and pull rope can arbitrarily elongate or shorten.When release cam 7 makes the clutch closure, clockwise rotate handle 9 this moment, pull rope is entangled on the reel 8, so hook 5 is mentioned, if hook bears a heavy burden, during release handle 9, reel 8 is irreversible under the effect of clutch, this moment, spring 10 and lead 11 tightly combined the flank of tooth of clutch, and be irreversible because the flank of tooth can clockwise rotate, so hook is still mentioned in the clockwise direction at any time when bearing a heavy burden.If desired hook is put down, open clutch and get final product.

Claims

1, a kind of powerful mechanical traction hook is made of column (1), capstan winch (2), pull rope (3), drag hook (4) and hook (5), and it is characterized in that: capstan winch (2) is made up of clutch (6), reel (8), handle (9); Hook (5) is board-like, and there is a toothrow shape pawl at the tip of hook.

2, a kind of powerful mechanical traction hook as claimed in claim 1 is characterized in that the clutch in the capstan winch (2) is the increment clutch.
