Embodiment 1

[0053] Structural Example 1: Two hemostatic components 1 are selected for combination. For more convenient combination, each hemostatic component only includes a pair of electrodes. Since the electrodes need to be energized and inserted into tissues, it is foreseeable that the electrodes are preferably made of metal, and the material selected in this embodiment is stainless steel. The electrodes are connected to the radio frequency host through cables, so that radio frequency energy flows between the working electrode 2 and the return electrode 3 . The radio frequency energy can be controlled by a foot-operated switch connected to the host, or by adding a manual switch in the hemostatic device to perform a manual switch.

Embodiment 2

[0054] Structural Example 2: The difference from Example 1 is that the electrode includes a straight tubular electrode body 201, one end of which is a closed tip; it also includes a shell for encapsulating the electrode, and the electrode body 201 The tip extends out of the casing; the casing is provided with a connecting piece that can cooperate with the casing of other hemostatic components 1 . In this embodiment, the connecting piece is arranged on the side wall of the casing, and after connection, all the electrodes are arranged in a straight line, and the working poles 2 and the return poles 3 are arranged in a staggered manner. The form of the connecting piece can be varied, as long as the two hemostatic components 1 can be firmly connected. In this embodiment, a mortise 8 is provided on the housing side wall of one of the hemostatic components, and a mortise 7 matingly connected with the mortise 8 is provided on the housing side wall of the other hemostatic component. ...

Abstract

The invention discloses a combined hemostasis apparatus. The combined hemostasis apparatus includes a plurality of hemostasis assemblies capable of being used in combination; each hemostasis assemblyis provided with at least one pair of electrodes used for electrifying hemostasis; each pair of electrodes includes a working pole and a circuit pole. According to the combined hemostasis apparatus provided with the structure, each hemostatic assembly can be used separately, and also in combination, the number of combinations is unlimited and the forms of the combinations are various, and the needs of ablation areas with different sizes and shapes can be satisfied; and the method of hemostasis can adopt inserting into tissue to conduct deep hemostasis, can further adopt flatting against on thetissue to conduct superficial large area hemostasis, and is suitable for various hemostasis situations.

Description

technical field [0001] The invention relates to a device for hemostasis, in particular to a hemostatic device that can be used in combination. Background technique [0002] Electrosurgical hemostatic instruments are often used in surgical operations, such as electric knife, electrocoagulation forceps, ultrasonic knife, electrocoagulation forceps, etc.; however, current electrosurgical instruments are usually used for surface hemostasis, and the hemostatic depth and hemostatic range are small. Hemostasis is less efficient during extensive excision procedures. Existing instruments for deep ablation, such as microwave ablation needles, only target tissue ablation in specific deep areas. Most of the ablation areas are spherical or ellipsoidal and other irregular shapes, which are inconvenient to cut and reduce surgical efficiency. In the actual operation, whether the hemostatic area is regular; especially, the cuboid hemostatic area that is easy to cut is very important to impr...
