Description

Tumor cutting tool

Technical Field

The utility model relates to a medical instrument specifically is a tumour cutting means.

Background

When medical personnel remove the operation of tumour to the patient through the minimal access surgery, medical personnel separate the internal tumour of patient from organizing the back, can meet the problem that the tumour volume after the separation is greater than the operation wound, can't follow the internal pocket of removing of patient with the tumour, medical personnel can follow the wound at present and pack up the tumour (avoid the tumour to fall into internal secondary diffusion that causes when shearing tumour), the back utilizes instrument such as clamp to tear out a small part with tumour from the wound position, cut off or cut off the tumour that presss from both sides with scalpel or operation scissors at last, cut off tumour tissue's volume to be enough to follow the operation mouth and remove finally.

Although the use of the above techniques enables removal of oversized tumours from a patient, there are disadvantages:

firstly, because the tumor tissue is hard (firm), the volume which can be torn out from the wound is small, so that the amount of the tumor tissue cut by a single time is small, the tumor can be continuously taken out from the wound by repeated cutting, and the operation time is long.

Secondly, the tumor tissue can extrude the wound when being pulled, so that the wound is expanded and the pain of the patient is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a tumour cutting means, be convenient for cut the too big tumour of volume, make the tumour volume diminish, remove from the patient is internal.

In order to achieve the purpose of the invention, the utility model adopts the following technical scheme: a tumor cutting tool is composed of two cutting devices, wherein each cutting device comprises a tool handle and a tool spoon, the tool spoons are used for cutting tumors, the cutting devices are in staggered rotatable connection, the rotary connection points of the cutting devices are located between the tool handles and the tool spoons, and the tool spoons can be mutually corresponding and covered; when the knife handles are close to each other, the knife spoon is close to each other at the same time; when the knife handles are far away from each other, the knife spoon is far away from each other at the same time.

Preferably, the cutting device further comprises a blade, the two ends of the blade are respectively connected with the knife spoon and the knife handle, and the blade is used for assisting the knife spoon in cutting and enabling the knife spoon to cut tumors far away from the knife handle.

Preferably, the handle, the blade and the spoon are detachably connected, so that the damaged blade and the damaged spoon can be replaced conveniently, and the handle can be replaced for preventing infection after the operation is finished.

Preferably, the handle of a knife is equipped with the through-hole, can stretch into the through-hole with the hand and hold the handle of a knife tightly, prevents that cutting device from dropping.

Preferably, the handle of a knife is equipped with the light, and the light is used for the illumination to be about to the tumour of cutting, and the medical personnel of being convenient for observe the accurate cutting of tumour.

Preferably, the knife handles are provided with the magnetic blocks, the magnetic blocks are arranged between the two knife handles, and the knife handles are mutually adsorbed through the magnetic blocks, so that medical staff can cut tumors more easily.

Compared with the prior art, the tumor cutting tool adopting the technical scheme has the following beneficial effects:

one, but alternate swivelling joint (similar scissors) each other between two cutting device, when medical personnel cut the tumour, two cutting device's power is used in two relative faces of tumour respectively, and the cutting is in towards the tumour, closes until the sword spoon lid mutually, consequently at cutting device single interlock in-process, the tumour tissue volume of cutting off is great, and the medical personnel of being convenient for cut the tumour, improves cutting efficiency.

Two, two knives and spoons are simultaneously cut the tumour from two directions, improve medical personnel's work efficiency, save the operation time that medical personnel cut the tumour and spend.

Three, two knives and spoons of tumour cutting means can directly enter into the cavity through the wound, need not to pull tumour tissue, avoid the wound to receive the pain that extrudees and bring, carry out the fly-cutting to tumour tissue through the sword and spoons, and the tumour tissue that cuts off is the fritter form basically, can take out the tumour tissue after the stripping and slicing with instruments such as tissue pincers at last can.
