Medical noninvasive skin anastomat

Abstract

The invention provides a medical noninvasive skin anastomat. The medical noninvasive skin anastomat comprises a front-end first substrate and a front-end second substrate, and a rear-end first substrate and a rear-end second substrate are oppositely arranged. A screw rod is arranged in a mounting groove formed in the rear-end first substrate in a penetrating manner, so that the rear-end first substrate can move along the front-end first substrate when the screw rod rotates; and vent holes communicate with an operation cavity. Racks are fixedly arranged on the front-end second substrate and the rear-end second substrate correspondingly, anastomosis force adjusting gears are engaged with the racks, ratchet wheels are fixedly arranged on a transmission rod I in a penetrating mode, and a clamping device is arranged on the side surfaces of the ratchet wheels. A ventilation blade is fixedly arranged on a central rod. The invention provides the medical noninvasive skin anastomat which is of a multi-section structure, the medical nonnvasive skin anastomat can anastomose a non-linear skin wound, can increase or decrease anastomosis tension, is easy to adjust and operate and good in skin ventilation effects, relieves discomfort of a patient and is very worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of medical staplers, in particular to a medical non-invasive skin stapler. Background technique [0002] Currently, there are generally two kinds of anastomotic techniques for skin incisions: one is invasive, such as: suturing techniques in various ways; suturing techniques of various materials (including skin nailing machines). The other is non-invasive anastomosis technology, such as: biological glue bonding technology; adhesive tape bonding technology. Disadvantages and clear-cuts of invasive anastomosis: Scars are easy to form, and even intradermal sutures will leave cord-like induration. Bioglue is a chemically synthesized glue that is applied between the sides of the wound. Because it is a foreign body tissue, it will also form cord-like induration. Moreover, the tensile strength is not enough, and the adhesive tape must be attached to the outside to tighten it. But single-use adhesive plaster will...

Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The above-mentioned device mainly adjusts the size of the anastomotic force through the elastic thread, but after a long time of use, the elastic thread will have problems such as decreased elasticity, looseness and damage, which makes the device 2. The above-mentioned device can only be applied to linear wounds, but due to the influence of factors such as different lesion locations and different patient body structures, the skin wounds may not be on the same straight line , so the scope of application of the above-mentioned device is very limited; 3. The part of the above-mentioned device that is in direct contact with the patient's skin is sealed. Since it takes a certain amount of time for the skin to heal, the time for the skin stapler to be close to the patient's skin is relatively long, but the above-mentioned The ventilation performance of the device is poor, which will not only affect the breathing of the skin, bring discomfort to the patient, but also affect the speed of wound healing
