マイクロメスに関するものである。[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is a disposable blade cartridge that is integrated with a protector that can limit the delicate cutting depth used in ophthalmic surgery. This relates to an attached ophthalmological micro scalpel.

したものは見当らなかつた。(Prior art) Micro scalpels for ophthalmic surgery have traditionally been used, especially for corneal incision surgery, to avoid the risk of the cutting edge cutting too far due to improper adjustment of the protruding length of the cutting edge, and to adjust it to the thickness of the cornea. There are disposable scalpels that are equipped with a protector that allows you to limit the cutting depth of the cutting edge, but I have not found any that have a protector integrated into the replaceable blade cartridge that is attached to the scalpel handle, making delicate handling operations easier.

It takes time and effort to accurately position the protruding amount of the cutting edge in accordance with the thickness of the cornea with micron-order precision, which inevitably puts a burden on the surgeon, and requires continuous use of this scalpel. In order to prevent the sharpness of the cutting edge from deteriorating and the need to recalibrate the measuring screw, as well as to prevent the infection of AIDS and hepatitis B virus to the operator, cleaning and sterilization after use is necessary for non-disposable cartridge types. There were also problems associated with handling, such as the fact that it was difficult to improve the reliability of products with complex structures.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, this invention has a protruding point of a cutting blade implanted at the tip of a replaceable blade cartridge which is provided with a removably attaching means on the head of a scalpel handle. A contact surface that can be formed into a protector that can limit the depth of cut by the tip is formed at the end of the cartridge body around the tip, and the protrusion length of the tip is accurately calibrated to have accuracy on the order of microns. The main body of the cartridge is made of a transparent resin material to make it easier to see around the cutting blade during operation, making it easier to handle, and the female handle to which the replacement blade cartridge is attached is made of a metal material to reduce the length of the replacement blade cartridge. It has an effective and economical configuration that makes it disposable.

でもよい。 In addition, while the cutting blade is fixed to the central shaft end of the double cartridge body, which is made by covering the replaceable blade cartridge body with a concentric outer cylinder, the cutting depth formed around the tip of the cutting blade can be limited. It may also have a configuration in which means is provided between the outer cylinder and the center axis to allow fine adjustment of the contact surface serving as the protector in the direction of the center axis so as to be freely removable.

科手術に効率的な利用ができる利点もある。 This idea is a disposable blade cartridge that can be detachably attached to the scalpel handle, with a means to facilitate delicate handling operations, and a protector that can limit the delicate cutting depth of the precise cutting blade is integrated into the cartridge. It is formed on the top of the main body and is made of a transparent resin material so that the tip of the cutting blade is easily visible, so that the cutting depth of the cutting edge can be adjusted to the thickness of the cornea when used for corneal incision surgery, etc. You can select a replacement blade cartridge with a protrusion length that can limit the protrusion length from the contact surface that serves as a protector, and the area around the tip of the cutting blade is easy to see, so you can operate with peace of mind, and the sharpness of the disposable blade is always guaranteed. This is highly effective in ensuring surgical accuracy and patient safety. Furthermore, since only the spare blade cartridge can be replaced, it is economical and has the advantage that it can be used efficiently in ophthalmic surgery by completely sterilized and hygienic disposable use.

によくなる。 In addition, instead of a set product in which the protruding length of the sharp end of the cutting blade is fixed and a replacement blade cartridge of different lengths is selected, the cartridge body can be made into a double type. By using a replaceable blade cartridge whose outer cylinder can be finely adjusted and fixed in a manner that allows it to be moved in and out, the economical effects of use are further improved.

て科すことができる。 FIGS. 1 and 2 show the head of a first embodiment of the ophthalmic microsurgical knife 1 of this invention. In FIG. 1, which shows cross-sections A and A' in FIG. An eye 25 is formed to allow the replaceable blade cartridge 4 to be easily attached to and detached from the knife handle 2. The tip 6 of the replaceable blade cartridge 4 has a shaft end finished so that the pointed end 8 of the cutting blade 7 protrudes from the shaft end, and the protruding length 9 from the shaft end surface 10 can be accurately calibrated to the required length on the order of microns. When inserting the tip 8 of the cutting blade 7 into the patient's cornea during corneal incision surgery, etc., the cutting depth is limited and the blade is handled delicately on a flexible surgical object. The shaft end surface 10 around the pointed end 8 of the cutting blade 7 can serve as a contact surface as a protector that can provide a sense of security to the doctor and patient.

カートリツジ４を選択することができる。 The replaceable blade cartridge 4 is made of polymethyl methacrylate resin and is transparent due to its excellent optical properties, and the periphery of the sharp end 8 of the cutting blade 7 is blocked by the shaft end 11 that serves as a protector, making it easy to perform surgical operations. Since it can be easily seen without getting in the way, handling becomes easier. Further, the scalpel handle 2 is made of an aluminum alloy material and is light and strong, and a disposable blade cartridge 4 can be detachably attached thereto. The replaceable blade cartridge 4 is constructed by combining an appropriate number of cutting blades 7 with different protrusion lengths 9 with dimensional differences of 10 microns as a set, thereby eliminating individual differences when measuring the thickness of the cornea, for example. In addition, an appropriate spare blade cartridge 4 can be selected.
