Description

Novel medical minimally invasive multi-plant hair transplantation fracture preset device

Technical Field

The utility model relates to the technical field of medical equipment, a novel medical minimally invasive hair transplantation crack preset operation instrument.

Background

At present, in the medical field of medical treatment, such as plastic surgery and beauty, when a patient needs to transplant hair, there is a method of first puncturing or cutting the scalp with a sharp surgical instrument, presetting a slit for the hair follicle to be transplanted, and then implanting the hair follicle. The existing medical surgical equipment (hereinafter referred to as the existing instrument) for transplanting the hair to form the gap in advance aims at a single hair, a single knife tip, a needle point or other sharp instruments are utilized to make a gap on the scalp to form the preset gap, and then the single hair follicle is planted manually.

The existing instrument can only preset one slit on the scalp skin at one time, so that only one hair follicle can be transplanted at one time. The use of existing instruments in hair transplantation requires the surgeon to repeat the same action many times. In the case of large-area hair transplantation, the same operation action of presetting the fracture needs to be repeated in a large number in the hair transplantation operation area (more than 8000 to 1 ten thousand times). Repeated operation for many times aggravates tissue injury, increases pain of patients, prolongs operation time, and increases risks of operation infection and complications. When the existing instrument is used, a doctor can only preset one crack once through the crack presetting operation, and the mode that the operation needs repeated operation actions for many times is adopted to finish the operation, so that the operation progress is seriously influenced, the operation time is prolonged, a large amount of manpower and material resources are wasted, and unnecessary injuries are caused to the spirit and the flesh of a patient.

Disclosure of Invention

In order to overcome the defect that one operation action of the existing instrument can only preset one hair follicle transplantation gap, the utility model provides a novel medical minimally invasive multi-plant hair transplantation gap presetting device (hereinafter referred to as presetting device), which can preset a plurality of gaps required by transplanting a plurality of plants of different operation areas through one operation action and is convenient to operate. This apparatus is when the operation, and the art field is distinguished clearly, can avoid soft tissue atress inequality, drawback such as extrusion each other, can obviously shorten the operation time, reduces the tissue wound, can obviously reduce the operation and bleed the infection probability, reduces the risk that operation complication takes place, practices thrift a large amount of manpower and materials, reduces to cause unnecessary injury to patient's spirit and flesh to improve operation doctor work efficiency, accelerate the operation progress, shorten the time that the hair transplanted in the accepting area, improve the hair survival rate greatly.

The utility model provides a its technical problem, the technical scheme who adopts is: the presetter comprises a tool apron, a handle, a protective cap, a plurality of tool bits and the like, wherein the tool bits are densely arranged according to a certain array and fixedly arranged on the tool apron, the tool apron and the handle are fixedly connected or integrally designed, and the protective cap can be tightly covered on the tool apron.

The width of the cutter head is 0.5-2 mm, the thickness is 0.5-1.5 mm, the height of the cutter head is 4.0-6.0 mm, the cutter head has double edges, and the tip of the cutter head is sharp, so that a micro-incision crack can be formed, and no trace is left after healing. The distance between the cutter heads is 1.0 mm-3.0 mm. A plurality of tool bits set up certain degree of depth department in the blade holder upper end through gluing, burying modes such as fixedly buried. The number of the plurality of cutter heads fixedly arranged on the cutter holder can be 2-n. By using the novel instrument, the number of the preset hair transplantation cracks in the hair transplantation operation accepting area can be 2-n by one action. Generally, the number of the cutter heads can be designed to be 2-80. A large number of cutter heads are utilized to preset a large number of cracks required by hair transplantation on scalp skin, so that the operation of transplanting hair is ensured to be rapid, time-saving and labor-saving.

The shape of the tool apron can be prism, frustum of prism, cylinder, round platform, etc.

The outer side wall of the tool apron is tightly matched with the inner side wall of the opening part of the protective cap or is connected in a mortise-tenon clamping mode and the like. When not in use, the protective cap is covered to protect the cutter head from being collided and accidental injury.

A handle is designed to facilitate holding and operating the instrument during operation. The handle and the tool apron can be designed integrally or separately, and when the split design is adopted, the handle and the tool apron are fixedly connected through threads or in forms of mortise and tenon and the like.

The material of the cutter head can be medical gem cutter head, medical stainless steel, medical titanium alloy and the like. The material of the cutter head is preferably medical gems. When the gem knife head is adopted, the knife edge is fine and smooth, the sharpness is high, the sapphire is colorless and transparent, and the precision degree of the operation is greatly improved. When the gem bit is adopted, because the sapphire is neutral and has stable physical and chemical properties, the influence on the nerve excitability is small, blood stains are not easy to adhere to, the sour blood is not soaked, and the gem bit is corrosion-resistant and easy to disinfect. When the gem knife is adopted, the formed fracture wound edge is smooth and perfect, healing is rapid, and no scar is left after operation.

The tool apron and the handle can be made of medical stainless steel, medical titanium alloy, medical silica gel, medical plastic and the like, and the protective cap can be made of medical plastic and the like.

The utility model discloses can have multiple length, multiple diameter, multiple model can suitably increase tool bit quantity according to the demand.

The utility model has the advantages that: a plurality of tool bits are arranged on the blade holder according to certain array is intensive, once handle, blade holder are pressed, can utilize a plurality of tool bits to preset simultaneously that the many hair follicles in different recipient areas transplant required a plurality of cracks, simple accurate safe and reliable, the art field is clear, makes things convenient for high-speed high-quality work of operation doctor. Compared with the existing apparatus which can only preset one crack at one time, the operation time of doctors and patients is obviously reduced, the doctor is prevented from repeatedly presetting the crack for multiple times to do the same action, the tissue wound is prevented from being aggravated by repeated operation for multiple times, the pain of the patient is prevented from being increased, and the operation time is prolonged. Use this apparatus when the operation, the doctor only needs to hand this apparatus handle, blade holder position, presses once, extracts, can accomplish and preset many plants hair follicle and transplant the crack action, obviously shortens the operating time, obviously increases hair transplantation postoperative survival rate, alleviates patient's unnecessary injury and misery, and the risk that greatly reduced hemorrhage infection and complication take place.
