Abstract

The utility model discloses a medical electric cutter absorbing smoke which is suitable for large-scale surgical operation, comprising a cutter head (electrode tip), a cutter holder, a cutter bar (electrode handle), and an electrode wire. The utility model is characterized in that the cutter head is clamped and fixed on the metal cutter holder; the cutter holder, the cutter bar, and the electrode wire are all hollow tubular structure, wherein, the pipe walls of the cutter bar and the electrode wire are all buried with conductor wires. The utility model has the advantages that the coke smoke which is generated during the burning or cutting operation is absorbed by the smoke absorbing mouth which is at the front end of the cutter head with negative pressure, so that the medical effect is enhanced and the surgical environment is improved.

Description

Medical electric cutter absorbing smoke

The utility model discloses a kind of medical high frequency electric knife, particularly a kind of Smoking pipe and high frequency electric knife be combined in a medical smoking electric knife on the whole, be applicable to large-scale surgical operation.

Existing Electric scalpel mainly is made up of cutter head (electrode tip), knife bar (electrode handle), electrode wires, as the KW65-3 type high frequency electric knife of Beijing Medical Instruments factory production.When high frequency electric arrives human body by electric knife, in tissue, produce heat effect, cut human body and make the tissue division under the electric knife reach several millimeters breach deeply, can make blood vessel be solidified to certain depth simultaneously, replace toe-in to prick, thereby shortened the time of operation greatly.But when electrosurgical cutting skin and subcutaneous tissue, produce a large amount of pungent unpleasant burnt cigarettes, both influenced the sight line of operation, polluted the environment of operating room again, increased the medical difficulty in the operation.

The purpose of this utility model is that a kind of improved Electric scalpel will be provided.It can also make the pungent unpleasant burnt cigarette that produces in the operation all absorb except that possessing characteristics such as electrotomy is easy, minimizing is hemorrhage fully easily, has improved medical effect, has improved surgical environments.

This utility model is finished as follows: cutter head (electrode tip) empennage bayonet socket is fastened on the tubular metal tool rest, and the threaded one end of metal tool rest and tubular knife bar (electrode handle) is fastened on the knife bar, and the other end of electrode wires and knife bar is pegged graft.Tool rest, knife bar, electrode wires are hollow tubular structures, wherein the tube wall of knife bar, the electrode wires conductor of being caught in ambush.After the electric knife attaching, the mouth of pipe with tool rest and cutter head junction that tool rest, knife bar and electrode wires have been formed a complete connection is the Smoking pipe of smoking port, and conductor and the lead in the electrode wires tube wall that while cutter head, metal tool rest and knife bar tube wall are hidden are linked to be a complete conductive path again.High frequency electric is hidden through hollow edged electrode line lead, knife bar sidewall when implementing electrotomy conductor, metal tool rest, cutter head enter patient's human body, in the tissue of human body, produce heat effect, cut human body, produce burnt cigarette simultaneously, at this moment burnt cigarette is absorbed by the hollow tubular tool rest smoking port that is connected to negative pressure source, reaches the smokeless purpose of electrotomy.This electric knife has improved the surgical medical environment, has alleviated medical personnel's labor intensity.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of this utility model.

With reference to Fig. 1, a metal cutter head (8) with magnetic tape trailer wing of excellent conductive performance and mechanical strength, empennage has an elongated gap, makes the empennage of cutter head (8) have elasticity.Tool rest (7) is the metal hollow tubular structure that a long 15mm external diameter is 14mm, there is screw thread one end inboard of metal tool rest (7), the other end begins tubular inner wall from end face and has symmetric twice sulculus, groove width 2mm, the empennage of metal electric knife head (8) can slide in groove, and sulculus has symmetric a pair of rectangle open-work (9) more inward.After the stressed gap of empennage of metal cutter head (8) narrows down, empennage advanced tool rest (7) sulculus, push inward cutter head (8) along sulculus, when the empennage of cutter head (8) arrives rectangle open-work (9), empennage enters the rectangle open-work (9) of tool rest (7) under the effect of self elastic force, cutter head (8) is connected on the metal tool rest (7) tightly.The end of thread of tool rest (7) is twisted and is connected on the knife bar (4).Knife bar (4) is a long 150mm, and the hollow tubular structures of internal diameter 10mm is made the tube wall copper conducting strip (5) of being caught in ambush by the insulation heat proof material.The two ends of knife bar (4) are revealed contact (3) that conducting strip (5) are arranged respectively and are the conducting ring of one (6) with conducting strip (5).The software electrode wires (1) of the other end of knife bar (4) and hollow tubular is pegged graft.The tube wall of electrode wires (1) braided wire (2) of being caught in ambush, fix an electrode wires metallic conduction ring (10) with electrode wires lead (2) conducting on electrode wires (1) and knife bar (4) grafting port, what be electrically connected when braided wire (2) in the electric wire (1) is pegged graft with knife bar (4) is firm.After electrode wires (1) and knife bar (4) are pegged graft like this, electrode wires conducting ring (10) just with knife bar on contact (3) connection.The other end mouth of pipe of electrode wires (1) connects negative pressure source, electrode cable (2) is drawn load onto plug simultaneously, inserts the high frequency electric source socket during in order to use.

During operation the electrode wires mouth of pipe and negative pressure source are connected, the electrode wires plug inserts in the input socket of high frequency electric source socket, negative electrode is bound in patient's shank, step on backpedalling brake high frequency electric output is promptly arranged on electric knife head (8), the burnt cigarette that produces when burning or cutting with cutter is all absorbed by the smoking-hole that has negative pressure on the tool rest (7), has realized that electrotomy and smoking carries out synchronously.

Claims

1, smoking electric knife of being made up of cutter head (electrode tip), knife bar (electrode handle) and electrode wires is characterized in that the empennage of cutter head is fixed on the tubular metal tool rest, and the metal tool rest is threaded with hollow knife bar, and the other end of electrode wires and knife bar is pegged graft.

2, smoking electric knife according to claim 1 is characterized in that knife bar is a hollow tubular structures, is embedded with metallic conductor in the tube wall, and the contact that metallic conductor is arranged is revealed at the two ends of knife bar respectively.

3, smoking electric knife according to claim 1 is characterized in that electrode wires is a hollow tubular soft body structure, buries deposited braided wire in the tube wall.
