However, in the prior art, as in the technical solution described in the above patent, although the electrocoagulation hemostatic scalpel and the surgical knife can be switched, the electrocoagulation hemostatic scalpel and the surgical knife are both independently moved, and when the switching is performed, a secondary operation is required, that is, when the electrocoagulation hemostatic scalpel is required to be used, the surgical knife needs to be operated first to retract the surgical knife, and then the electrocoagulation hemostatic scalpel needs to be operated to extend to the operation position; when the scalpel is required to be used, the electrocoagulation hemostatic scalpel needs to be operated firstly to be retracted, and then the hemostatic scalpel needs to be operated to extend to the operation position. In other words, when switching is performed, two surgical tools need to be operated successively, which is inefficient.

In view of this, the designer has designed an electricity congeals hemostatic knife, not only has two kinds of functions that can switch each other of electricity congeals hemostasis and operation cutting, still has the simple operation flexibility, labour saving and time saving, improves the advantage of operation efficiency.

Referring to FIG. 1 or FIG. 3, in the present embodiment, the electrocoagulation hemostatic scalpel comprises a housing 100, an electrocoagulation scalpel body 200, a scalpel body 300 and a linkage 400.

When one of the electrocoagulation cutter body 200 and the surgical cutter body 300 moves in a first direction 001, the other of the electrocoagulation cutter body and the surgical cutter body is driven by the linkage mechanism 400 to move in a second direction 002 opposite to the first direction 001; the electrocoagulation knife body 200 or the surgical knife body 300 can extend out of the operation port 120 when moving along the first direction 001, and the electrocoagulation knife body 200 or the surgical knife body 300 can retract into the accommodating cavity 110 when moving along the second direction 002.

The working principle of the electrocoagulation hemostatic knife provided by the embodiment is as follows:

referring to fig. 1 and 3, it is set that, in the initial state, the ends, i.e., the front ends, of the electrocoagulation knife body 200 and the surgical knife body 300 close to the operation port 120 are flush and both are located in the accommodation chamber 110. When the electrocoagulation knife body 200 is needed, force is applied to the linkage mechanism 400 at this time, so that the electrocoagulation knife body 200 moves along the first direction 001, the front end of the electrocoagulation knife body 200 gradually extends out of the operation port 120, and meanwhile, the surgical knife body 300 continues to retract into the accommodating cavity 110 along the second direction 002. After the electrocoagulation cutter body 200 extends to a set position, the electrocoagulation hemostasis operation is carried out. When the surgical knife body 300 needs to be used, the same force is applied to the linkage mechanism 400, so that the surgical knife body 300 moves along the first direction 001, the front end of the surgical knife body 300 gradually extends out of the operation opening 120, and meanwhile, the electrocoagulation knife body 200 retracts into the accommodating cavity 110 along the second direction 002. When the surgical knife 300 is extended to a predetermined position, the tissue cutting operation is performed.

In the operation process, the electric coagulation knife body 200 and the operation knife body 300 are in linkage operation, one of the electric coagulation knife body and the operation knife body is operated, the other electric coagulation knife body and the operation knife body respond in time to perform corresponding actions, and the electric coagulation knife is convenient and flexible to operate, time-saving and labor-saving and high in efficiency.

It should be understood that the operation principle of the electrocoagulation knife body 200 is the prior known technology, that is, the electrocoagulation knife mainly coagulates small blood vessels by high-frequency current, and coagulates and carbonizes blood by the action of electric heat, so as to achieve the purpose of hemostasis, and how to implement the principle and structure of hemostasis for the electrocoagulation knife body 200 is not described in this embodiment again.

In addition, in the initial state, one of the electrocoagulation knife body 200 or the surgical knife body 300 can be in a position extending out of the operation port 120, so that the surgical operation can be performed without switching operation in some occasions, and the efficiency is improved. For example, the surgical knife body 300 may be configured to extend out of the operating port 120 in an initial state.

In this embodiment, optionally, the casing 100 is an elongated casing, the casing 100 has a front end and a rear end in a length direction thereof, the front end is an end close to the patient, the rear end is the other end opposite to the front end, the operation opening 120 is disposed at the front end, that is, the front end is disposed in an open structure.

Referring to fig. 1 and fig. 2, further, the housing 100 is provided with an assembly hole 170, a first sliding groove 130 and a second sliding groove 140. The fitting hole 170 is a cylindrical hole, and the fitting hole 170 extends in a third direction perpendicular to the first direction 001 or the second direction 002. First spout 130 and second spout 140 are the rectangular channel, and first spout 130 and second spout 140 are parallel and the notch of the two sets up relatively, and first spout 130 and second spout 140 all extend along the straight line in first direction 001 or second direction 002 place.

Moreover, the end cap 500 is detachably connected to the front end of the housing 100, for example, the end cap 500 may be snapped into the operation opening 120 in an interference fit manner, and the end cap 500 may have a certain deformation capability, so as to be snapped into the operation opening 120. When the end cap 500 is attached to the housing 100, portions of the end cap 500 can extend into the open sides of the first and

second chutes

130, 140, such that the end cap 500 can prevent the electrocoagulation blade body 200 and the surgical blade body 300 from sliding out of the procedure port 120. Meanwhile, the end cap 500 is provided with a first through hole 510 and a second through hole 520 which are independent of each other, the first through hole 510 is used for the coagulation knife body 200 to penetrate, and the second through hole 520 is used for the surgical knife body 300 to penetrate.
