Abstract

The utility model discloses a pair of brain tumor extirpation forceps. The brain tumor extirpation forceps comprise a handle and forceps arms, wherein an adsorption device is arranged at the front ends of the forceps arms, a hollow guide pipe is arranged in the forceps arms, one end of the hollow guide pipe is communicated with the adsorption device in sealing mode, the other end of the hollow guide pipe stretches out of the forceps arms, and an air valve and an air outlet which is communicated with the outside world are sequentially arranged on the hollow guide pipe. The adsorption device is a sucking disc. When a user uses the brain tumor extirpation forceps, the user first uses the front ends of the forceps arms of the brain tumor extirpation forceps to gently clamp a brain tumor, communicates the air outlet with an external negative pressure generation device, and then opens the air valve, then negative pressure is generated in the sucking disc, and the sucking disc adsorbs the brain tumor onto the brain tumor extirpation forceps, and accordingly the problems that the tumor is difficult to clamp when applied force is small, and peripheral tissue is injured and even the brain tumor is broken when the applied force is large are avoided.

Description

A kind of cerebral tumor enucleation forceps

Technical field

This utility model belongs to technical field of medical instruments, relates in particular to a kind of cerebral tumor enucleation forceps.

Background technology

The cerebral tumor is one of disease common in nervous system, and in recent years, cerebral tumor sickness rate is in rising trend, in treatment, generally by surgical operation, intracranial tumor is extractd.It for portion of external, is the cerebral tumor of one deck peplos, when operation, first with bipolar electrocoagulator or micro-shears, the cerebral tumor is extractd, the ablation of tumors of requiring mental skill again clamps to clamp the cerebral tumor, because the inside of tumor is the rare soft tumor tissue of quality, while holding tumor with conventional ablation of tumors clamp in operation, too little being not easy of chucking power clamped tumor, chucking power may well injure perienchyma very much, if tumor is clipped broken, not only increased the difficulty of operation, more likely because tumor is removed not thorough, or pollute other cerebral tissue, and increased the recurrence probability after ablation of tumors.

Summary of the invention

It is not by the chucking power clamping cerebral tumor that the technical problems to be solved in the utility model is to provide a kind of, but cerebral tumor enucleation forceps tumor being held by the absorption affinity of adsorbent equipment.

For solving the problems of the technologies described above, this utility model is to be achieved through the following technical solutions: a kind of cerebral tumor enucleation forceps, comprise handle and tong arm, the front end of tong arm arranges adsorbent equipment, hollow conduit is set in tong arm, one end of hollow conduit is communicated with adsorbent equipment sealing, and the other end stretches out outside tong arm, and the gas outlet that is disposed with air valve and is in communication with the outside.

Described adsorbent equipment is a sucker.

Described adsorbent equipment is comprised of a plurality of suckers.

This utility model is fixedly installed adsorbent equipment by the front end at tong arm, when extracing tumor, rely on absorption affinity that tumor is adsorbed onto on enucleation forceps, and no longer rely on chucking power to clamp tumor, thereby avoided firmly too little being not easy that tumor is clamped, firmly may well injure perienchyma very much, even tumor be clipped broken.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structure for amplifying schematic diagram after this utility model sucker place further improves.

The specific embodiment

Below in conjunction with attached Fig. 1 and 2, this utility model is elaborated:

As shown in Figure 1, a kind of novel cerebral tumor enucleation forceps, comprise handle 1 and tong arm 2, the front end of tong arm 2 is fixedly installed adsorbent equipment 3, the interior hollow conduit 4 that arranges of tong arm 2, one end of hollow conduit 4 is communicated with adsorbent equipment 3 sealings, and the other end stretches out outside tong arm 2, and the gas outlet 6 that is disposed with air valve 5 and is in communication with the outside.Described adsorbent equipment 3 is suckers.During use, tong arm 2 front ends of the ablation of tumors of first requiring mental skill pincers are clamped the cerebral tumor lightly, gas outlet 6 and extraneous negative pressure generating device are connected, open air valve 5, in sucker, can produce negative pressure and the cerebral tumor is adsorbed on cerebral tumor enucleation forceps, then air valve 5 is closed, tumor just can unanimously be adsorbed on cerebral tumor enucleation forceps.Extract after tumor, then open air valve 5, in sucker 3, there is no negative pressure, tumor will fall down from enucleation forceps automatically.Thereby avoided firmly too little being not easy that tumor is clamped, firmly may well injure perienchyma of perienchyma very much, even the cerebral tumor has been clipped broken.

Further, as shown in Figure 2, described adsorbent equipment 3 is comprised of a plurality of suckers 7, like this, just more easily the cerebral tumor is adsorbed on cerebral tumor enucleation forceps firmly.

Claims

1. a cerebral tumor enucleation forceps, comprise handle (1) and tong arm (2), it is characterized in that: the front end of described tong arm (2) is fixedly installed adsorbent equipment (3), hollow conduit (4) is set in tong arm (2), one end of hollow conduit (4) is communicated with adsorbent equipment (3) sealing, the other end stretches out outside tong arm (2), and the gas outlet (6) that is disposed with air valve (5) and is in communication with the outside.

2. cerebral tumor enucleation forceps according to claim 1, is characterized in that: described adsorbent equipment (3) is a sucker.

3. cerebral tumor enucleation forceps according to claim 1, is characterized in that: described adsorbent equipment (3) is comprised of a plurality of suckers (7).
