Description

Block surgical knife

The present invention relates to a tackle surgical knife, and more particularly to a cutter for cutting a pulley and for treating a trigger finger surgery.

Because everyone has a lot of opportunities to use finger movements in daily life, such as work, computer, palm-type electrical appliances, text messaging, writers, sports, etc., it is easy to cause excessive finger use and trigger The lesions often occur at the volar side of the joint between the metacarpal and the proximal phalanx. Each finger may occur, and the cause is that the stenosis becomes thicker or the tendon has nodules after the tendon is inflamed. The bulging bulge causes the tendon to slide freely in the trochlear joint at the joint, causing pain, and as the disease progresses, the finger cannot straighten or bend smoothly. In severe cases, surgery must be performed to improve the trigger finger. Symptoms.

The scalpel currently used to treat the trigger finger has the "Mini-Invasive Trigger Surgical Knife Structure" of the Republic of China No. M302351, comprising a set of shells, a linkage knife seat, a driving member and a cutter; the front end of the casing has a a hook-shaped member, the interlocking knife seat is disposed inside the casing, the driving member is movably connected to the interlocking blade seat, the cutter is connected to the front end of the interlocking blade seat; and the hook member is used to hook the A1 pulley Then, the driving piece drives the interlocking knife holder to advance together with the cutter to achieve effective positioning, so that the cutter cuts the A1 pulley to complete the operation, however:

Although it has the effect of positioning the infeed amount, it still has no need to accurately position the cutting angle. It still needs the experience of the auxiliary instrument or the doctor. In addition, when cutting the pulley, it is the same as the general minimally invasive tackle surgical tool. Cut the pulley only, but when the pulley is too thick, the tendon and the pulley are too narrow. If the pulley is only cut, the improvement effect will not be expected. At this time, the traditional surgical method is still needed to cut the affected part of the skin. Partial resection of the affected part results in a traditional surgical procedure with excessive wounds, a long recovery time, and easy damage to the missing nerves or tissues of the hand.

Accordingly, it is an object of the present invention to improve the aforementioned deficiency.

According to the above object of the present invention, the present inventors have developed a tackle surgical tool based on the spirit of continuous innovation and research and development, including:

a main body having opposite ends, one end of which is an isolation section, and the other end is a holding section, the end of the isolation section is bent to form a blocking portion; a fixing component is extended from the holding section of the main body to the isolation section a blocking portion; a body having a long strip shape with a groove connecting the two ends, and forming a two cutting piece at one end thereof, the body extending from the holding portion of the body into the isolation portion The blocking portion blocks the two cutting pieces from the blocking portion and causes the fixing member to be covered by the groove.

Further, the blocking portion has a bending angle of 30 degrees to 50 degrees, and the two cutting pieces of the cutter body form the same bending angle and are attached to the blocking portion.

Further, the holding portion of the main body is provided with two positioning through holes, and the fixing member and the cutter body respectively extend from the two positioning through holes to the isolation portion.

Further, the isolation section of the main body has a guiding groove, so that the fixing component is guided by the guiding groove when extending into the isolation section, and is located on the guiding groove.

Further, the blocking portion of the isolation portion has a through hole, and the end portion of the fixing member forms a conical section, and the conical section passes through the through hole, so that the fixing member abuts against the periphery of the through hole.

The main effects of the present invention are:

1. The surgical knives of the present invention extend from the finger-hand boundary to the affected part, and do not contact the palm of the nerve. The invasiveness is low, and the resistance to the surgery and the possibility of damage to the palm nerve are reduced. To the lowest.

2. The invention utilizes the main body to pass between the tendon and the trochle, and then cooperates with the fixing component to press the affected part to be removed, so that the body can accurately remove the affected part, and since the tendon is separated from the trochle, the tendon is not damaged, and the operation is performed. High precision and not easy to relapse.

3. After the operation is completed, the affected part can be taken out together with the surgical tool to facilitate the pathological observation of the affected part.

Combining the above technical features, the main effects of the present invention will be clearly shown in the following embodiments.

Referring to the first and second figures, the utility model relates to a sliding surgical tool, which comprises a main body (1), a fixing component (2) and a cutter body (3), and then please refer to the third figure and the fourth figure. As shown in the figure, the instructions are as follows:

The main body (1) has opposite ends, one end of which is an isolation section (11), and the other end is a holding section (12) having a guiding groove (111) on the isolation section (11), and in the isolation section ( 11) The end portion is bent at about 30 degrees to 50 degrees to form a blocking portion (112), the blocking portion (112) has a through hole (113), and further disposed on the holding portion (12) Positioning the perforation (121), during surgery, first cutting a small gap (A1) for the isolated section (11) of the body (1) into the front end of the affected part of the finger (A), after which The isolation section (11) of the main body (1) is extended from the small gap into the affected part of the finger (A), and the isolation section (11) is passed between the tendon (A2) and the pulley (A3), thereby applying the tendon (A2) is separated from the pulley (A3) so that the subsequent resection does not damage the tendon (A2). At the same time, the finger (A) position extends into the affected part of the palm, and does not touch the palm of the nerve. Low, minimizing the resistance to surgery and the possibility of damage to the palmar nerves.

The end of the fixing element (2) forms a conical section (21). When the isolation section (11) of the main body (1) enters the affected part of the finger (A), the fixing element (2) is supported by the holding section (2) 12) One of the two positioning perforations (121) projects into the isolation section (11) and is guided by the guide groove (111) to correctly extend the fixing element (2) into the isolation section (11) a blocking portion (112), and passing the conical section (21) through the through hole (113), so that the fixing member (2) abuts against the periphery of the through hole (113), whereby the fixing member can be made (2) Stable to the affected part to be removed as a fixation and positioning.

The cutter body (3) is of a long strip shape, and is provided with a groove (31) communicating with the two ends, and a second cutting piece (32) is formed at one end thereof, and the two cutting pieces (32) form the same block. The bending angle of the portion (112), when the fixing member (2) protrudes into the affected portion of the finger (A) and fixes and positions the affected portion to be removed, the blade body (3) is grasped by the holding portion (12) Another positioning through hole (121) extends into the blocking portion (112) of the isolation portion (11) such that the two cutting pieces (32) are blocked by the blocking portion (112) and abut against the blocking portion (112). And the fixing element (2) is covered by the groove (31), whereby the body (3) is guided by the fixing element (2) and correctly protrudes into the isolation section (11) Blocking portion (112).

Referring to the fourth and fifth figures, finally, the main body (1) is slowly extracted from the finger (A) together with the fixing member (2) and the body (3). At this time, the body is (3) The second cutting piece (32) will cut off the part to be cut off by the pulley (A3), and is taken out from the finger (A) for convenient pathological observation.
