description of reference numerals: 1. the device comprises an operating handle, 2, an insulating tube, 2A, a limiting clamping block, 3, an electric hook, 4, a pipette, 5, a functional sleeve, 5A, a cavity, 5B, an air suction hole, 5C, a connecting pipe, 6, a negative pressure suction device, 7 and an elastic clamping piece.

Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

example (b):

referring to fig. 1, the present embodiment provides a multifunctional electric hook for laparoscopic surgery, which includes an operation handle 1, an insulating tube 2 installed at an end of the operation handle 1; the electric hook 3 penetrates through the insulating tube 2 and is connected with the operating handle 1; a pipette 4 is arranged on the insulating tube 2 along the direction parallel to the axis of the insulating tube 2, and a functional sleeve 5 is sleeved outside the insulating tube 2; a cavity 5A is formed in the middle of the functional sleeve 5, and an air suction hole 5B communicated with the cavity 5A is formed in the side wall of the functional sleeve 5; the connection tube 5C and the pipette 4 provided at the upper end of the cavity 5A are detachably connected to the negative pressure suction means 6, respectively. The negative pressure suction device in the embodiment is a medical electric negative pressure machine which can be washed and disinfected.

An elastic clamping piece 7 is further arranged between the electric hook 3 and the operating handle 1, and the electric hook is movably arranged in the insulating tube 2 through the elastic clamping piece 7. After the elastic clamping piece 7 controls the electric hook 3 to move towards the inside of the insulating tube 2, the difference between the extending amounts of the pipette 4 and the electric hook 3 from the end part of the insulating tube 2 is not more than 5 mm. The elastic clamping piece 7 can control the advance and retreat of the electric hook 3 in the insulating tube 2, so that the pipette 4 can be separated to work in the retraction state of the electric hook 3 without interference from the electric hook 3, and the elastic clamping piece 7 used in the embodiment is a pressing type telescopic structure, and the specific structure of the elastic clamping piece is similar to that of a piston and a lantern flower expansion body in the publication No. CN110432979A or that of a telescopic switch in the publication No. CN 209884322U.

The position, close to the electric hook 3, on the outer side wall of the insulating tube 2 is provided with a limiting clamping block 2A with the size corresponding to the functional sleeve 5, and the functional sleeve 5 is movably arranged on the insulating tube 2. Because the detachability of function sleeve pipe will be guaranteed, so there is the problem that function sleeve pipe probably deviates from the lower extreme of insulating tube 2, and uses spacing fixture block 2 can effectively prevent this phenomenon.

Referring to fig. 3, the insulating tube 2 is a straight tube with a semicircular section; the inner pipe structure of the function sleeve 5 is matched with the outer pipe wall of the insulating pipe 2, and the cavity 5A is arranged on one side, right opposite to the insulating pipe 2, of the function sleeve 5. The inner and outer walls of the insulating tube 2 and the functional sleeve 5, which are fitted with each other, can prevent the insulating tube 2 from rotating in the functional sleeve 5, thereby avoiding inconvenience in the surgical procedure.

The connection tube 5C is detachably attached to the cavity 5A, and the structure of the end side of the connection tube 5C is the same as that of the tip of the pipette 4. The functional sleeve 5 is made of transparent medical plastic.
