Abstract

The utility model relates to medical equipment, in particular to a pair of novel special electric coagulation forceps for brain surgery, which comprises a metal forceps body consisting of a forceps handle, a forceps arm and a forceps tip, an insulating forceps seat wrapped at the rear end of the forceps body, a lead wire led out of the forceps seat and a socket, wherein insulating layers are wrapped on the surfaces of the forceps handle and the forceps arm except for the exposed forceps tip. The pair of novel special electric coagulation forceps is characterized in that the front end of the forceps arm extends to the forceps tip, and is arc-shaped from front view and flat from overhead view. The pair of novel special electric coagulation forceps has the beneficial effects that the arc-shaped front end of the forceps arm and the forceps tip can probe along a tumor and normal brain tissue for electric coagulation, cut off all blood vessels and tissue which are connected with the tumor by electric coagulation in blindness, and then conduct tumor excision by blocks, so as to greatly reduce the amount of bleeding in the process of operation, greatly avoid the injury of the normal brain tissue, and be beneficial to the smooth conduction of the operation and postoperative rehabilitation, and good in operation effect without sequelae.

Description

The special-purpose electric coagulation forceps of novel cerebral surgery operation

Technical field:

This utility model relates to medical apparatus and instruments, relates generally to the cerebral surgery operation apparatus, particularly the meningioma special-purpose electric coagulation forceps of performing the operation.

Background technology:

Meningioma is the common entity tumor of a kind of intracranial, and the tumor body is circle or elliptical shape, clear border, and its peripheral blood after the excision mode is out that cranium finds the tumor body, adopts bipolar coagulation for abundant, by outwards piecemeal excision in the tumor, the electric coagulation hemostasis while excising.Its tweezer arm of present employed bipolar coagulation forceps to tweezer point is straight, and circular tumor body is wrapped in the normal cerebral tissue, during operation along normal cerebral tissue and tumor body border electricity coagulate peripheral blood for the time, can only block the outer 1/3 blood confession that the tumor body exposes with fixed attention by electricity, when coagulating for other position electricity of tumor, straight tweezer point can not probe into electricity along the arc tumor boundaries and coagulate, and tends to tractive and destroys normal cerebral tissue, causes tissue injury and operation sequela.

Summary of the invention:

Goal of the invention of the present utility model is to overcome the defective that has the straight-arm electric coagulation forceps now, provides a kind of novel cerebral surgery operation special-purpose electric coagulation forceps, its anterior sagittal, during operation and tumor boundaries match, can coagulate the blocking-up hemostasis along tumor and normal cerebral tissue border electricity, do not destroy normal cerebral tissue.

For reaching the technical scheme that the foregoing invention purpose taked be, the special-purpose electric coagulation forceps of novel cerebral surgery operation, comprise the metal tweezer body that constitutes by tweezer handle, tweezer arm, tweezer point, be wrapped in the insulation tweezer seat of tweezer body rear end, the lead and the socket of being drawn by the tweezer seat are except that exposed tweezer point, tweezer handle and tweezer arm appearance wrap insulating barrier, be characterised in that tweezer arm front end prolongs and main the looking of tweezer point is arcuation, overlooks flat.

The beneficial effect that this utility model produced is, be arcuation tweezer arm front end and tweezer point, can probe into electricity with fixed attention along tumor and normal cerebral tissue border, cut off all and the blood vessel and the tissue of tumor bulk phase company with fixed attention at the blind following electricity looked, and then the piecemeal tumor resection, can significantly reduce the operation process amount of bleeding, avoid greatly normal brain tissue injury, help operation and carry out smoothly and postoperative rehabilitation, do not stay sequela, good operation effect

The specific embodiment:

Attached Fig. 1 and 2 has provided the front view and the vertical view of a specific embodiment of this utility model.The special-purpose electric coagulation forceps of this novel cerebral surgery operation comprises the metal tweezer body that is made of tweezer handle 1, tweezer arm 2, tweezer point 3, is wrapped in the insulation tweezer seat 4 of tweezer body rear end, and by lead 8 and socket 9 that the tweezer seat is drawn, except that exposed tweezer point, tweezer handle and tweezer arm appearance wrap insulating barrier 7.The electric coagulation forceps of prior art, its tweezer arm to tweezer point is straight, employed straight-arm electric coagulation forceps as shown in accompanying drawing 5, carry in its defective such as the background technology, straight tweezer point can not probe into electricity along the arc tumor boundaries and coagulate, and often tractive destroys normal cerebral tissue, causes tissue injury and operation sequela.The contribution that this utility model is done is, tweezer arm 2 front ends are prolonged and tweezer point 3 is made arcuation, promptly main looking is arcuation, overlook flatly, this new front arc electric coagulation forceps can probe into electric coagulation hemostasis along circular tumor and normal cerebral tissue border, as shown in Figure 6, block all and the blood vessel and the tissue of tumor bulk phase company with fixed attention at the blind following electricity looked, significantly reduce the operation process amount of bleeding, can avoid greatly normal brain tissue injury.Reference numeral 5 is the fixing spacing block of tweezer seat in the accompanying drawing, and Reference numeral 6 is a limited block, and Reference numeral 10 is a tumor.

Claims

1. the special-purpose electric coagulation forceps of novel cerebral surgery operation, comprise the metal tweezer body that constitutes by tweezer handle (1), tweezer arm (2), tweezer point (3), be wrapped in the insulation tweezer seat (4) of tweezer body rear end, the lead (8) and the socket (9) of drawing by the tweezer seat, except that exposed tweezer point, tweezer handle and tweezer arm appearance wrap insulating barrier (7), it is characterized in that, tweezer arm (2) front end prolongs and main the looking of tweezer point (3) is arcuation, overlooks flat.
