Embodiment 1

[0020] like Figure 1-2 As shown, the present invention provides a multifunctional hemostat for hepatobiliary surgery, including a heating head 1 and a handle 2, the heating head 1 is screwed to the front end of the handle 2 through a connecting head 3, and the heating head 1 and the connecting head 3 are Integrated structure; the heating head 1 is a quadrangular pyramid structure with an open bottom end, and the hemostatic gauze 101 is bonded to the conical surface of the heating head 1, which can be replaced after use. The heating head 1 is provided with a heating wire 102 inside, The heating wire 102 is arranged along the inner wall of the heating head 1, and the heating head 1 is made of stainless steel;

[0021] The handle 2 is a hollow structure, and a separator 210 is horizontally arranged in the handle 2, and divides the inside of the handle into a diversion area and a circuit area from top to bottom, and the diversion area is provided with a pumping tube 201, so One ...

Embodiment 2

[0024] The difference between embodiment 2 and embodiment 1 is that calcium alginate sponge is bonded to the pyramid surface of the heating head 1 .

[0025] Before use, connect the suction tube 201 and the catheter tube 203 to the negative pressure aspirator and the suction pump respectively. Bleeding port, then turn on the suction pump, introduce physiological saline to the wound through the catheter 203, finally rotate the temperature adjustment knob switch 207, the temperature display block 209 can display the set temperature, turn the temperature adjustment knob switch 207 to a suitable temperature, At this time, the heating wire 102 is heated, and the conical surface of the heating head 1 is placed on the wound. On the one hand, after the calcium alginate sponge is applied to the wound, the calcium ions in the calcium alginate can interact with the sodium ions in the wound exudate and blood. Exchange and release calcium ions, which can promote blood coagulation. On the o...

Embodiment 3

[0027] like image 3 As shown, the difference between embodiment 3 and embodiment 2 is that the heating head 1 has a triangular pyramid structure, and the heating head 1 is made of copper.

Abstract

The invention provides a multifunctional hemostat for the department of hepatobiliary surgery, and belongs to the field of medical instruments. The multifunctional hemostat for the department of hepatobiliary surgery comprises a heating head and a handle, wherein the heating head is connected with the front end of the handle in a matched manner through a connector; the heating head has a conical structure with an opening in the bottom end; a hemostasis block is arranged on a conical surface of the heating head; a heating wire is arranged in the heating head; the handle has a hollow structure; a temperature regulator, a liquid sucking tube and a liquid guiding tube are arranged in the handle; the temperature regulator is electrically connected with the heating wire and is connected with a power wire; a temperature regulating knob switch, a power supply indicator lamp and a temperature displaying block are arranged on the handle; and the temperature regulating knob switch and the temperature displaying block are separately connected with the temperature regulator electrically. By the thermal effect generated by a resistance wire, biological tissues or blood vessels are dewatered and coagulated to achieve the purpose of hemostasis, and therefore, the problems that smoke is easily generated in an electric coagulation hemostasis process, radiation exists and thermal loss is large are solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional hemostat for hepatobiliary surgery. Background technique [0002] Clinically, when performing hepatobiliary surgery on a patient, the wound needs to be hemostasis immediately after cutting the surface with a scalpel. At present, the commonly used method of hemostasis is electrocoagulation. Electrocoagulation can be divided into unipolar electrocoagulation and bipolar electrocoagulation. , the working principle of monopolar electrocoagulation is to use the high-frequency current of the monopolar electrosurgical unit to form a complete circuit through the electrosurgical head, human tissue and the patient's plate. During electrocoagulation, the tissue cells are rapidly dehydrated and coagulated to achieve hemostasis; The working principle of bipolar coagulation is to apply high-frequency high-power sine waves, which are released through the two...
