Description

It is a kind of to include knife for include tophus

Technical field

Include knife the utility model relates to one kind, in particular to it is a kind of to include knife for include tophus, belong to medical instrument skill Art field.

Background technique

Tophus is a kind of tubercle as hard as flint, is Monosodium urate crystallization deposition on soft tissue, can cause chronic inflammation And proliferation of fibrous tissue forms tubercle swelling, brings patient suffering, existing solution is to remove tophus using operation, this That there are wounds is relatively large for method, and recovery time is relatively long, also has using minimally invasive needle knife videoendoscopic surgery, can effectively reduce to disease The wound of people, but in minimally invasive needle knife videoendoscopic surgery, there is no the tools for removing tophus, how effectively to remove tophus, this It is problem to be solved.

Summary of the invention

Technical problem to be solved by the utility model is: provide it is a kind of include knife for include tophus, it can be by including Blade on knife includes the tophus for including to get off except the tophus on soft tissue under the action of negative pressure, by hollow on knife handle Channel is sucked away, and will not pollute the soft tissue of patient, and easy cleaning, structure is simple, easy to operate, is solved above-mentioned Technical problem.

The technical solution of the utility model is: a kind of to include knife for include tophus, it includes knife handle and blade, the knife Handle is cylindrical rod-like structure, and centre is hollow form, and front end outer side has several blades, and end is connected with end socket, the knife It is fixedly connected between sword and end socket and knife handle, several through-holes is equipped between the circumference upper knife edge of knife handle, connected in the rear end of knife handle It is connected to hose, the vacuum system connection of hose and hospital, including the tophus removed can be siphoned away by negative pressure, and operation is very easy.

The blade is sheet, along knife handle axial direction twist or circular ring shape.Using the blade included on knife It includes except tophus.

The end socket is semi-spherical shape.Smooth outer surface will not cause to damage to soft tissue.

The blade with a thickness of 1mm, be highly 2mm, axial spacing be 5~7mm.

The outer diameter of the knife handle is 4~5mm, and wall thickness is 1~1.5mm.

One layer of rubber sleeve is equipped on the outside of the rear end of the knife handle.Can be anti-skidding, it is easy to operate.

The diameter of the through-hole is 2mm.Tophus is sucked away by through-hole, will not be polluted.

The material of the knife handle, blade and end socket is stainless steel.

The beneficial effects of the utility model are: compared with prior art, the utility model is simple and reasonable, facilitates reality With, it can be included except tophus using the blade included on knife, and can be siphoned away by negative-pressure pipeline, one layer of rubber sleeve is used on knife handle, Can be anti-skidding, stable operation can remove tophus completely, and such minimally invasive wound of operation can mitigate the pain of patient, And can once remove completely, future trouble is not had, extraordinary using effect is achieved.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment
