Description

Protective incision tool for loosening ligament of wrist joint syndrome

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a protective incision knife tool for loosening ligaments by wrist joint syndrome.

Background

The medial nerve passes through the elbow and into the palm of the hand, and the "carpal tunnel syndrome" is the syndrome of compression on the wrist due to the median nerve from the arm to the fingers. After the median nerve is compressed, the three fingers, thumb, index finger and middle finger, which are "guided" by the median nerve, will first produce pain and numbness. The small muscles of the hand under the control of the finger atrophy, so that the phenomena of 'claw-shaped hands' (the little finger and the ring finger cannot be straightened), incapability of holding the palm of the thumb, incapability of holding the fingers of the thumb and the index finger, incapability of separating and closing the fingers and the like appear.

At present, the traditional incision knife used for ligament release of wrist joint syndrome has large volume, influences the operation visual field, has large damage to patients, and can cause scars due to overlarge open wounds of hands.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve lies in: provides a protective incision tool for loosening ligament in wrist joint syndrome, which solves the problems in the prior art.

In order to solve the technical problem, the technical scheme of the utility model is that: a protected incision knife apparatus for wrist joint syndrome release ligament is used, including handle, guiding mechanism, conical head, coupling mechanism, anti-skidding stripe, handle outer wall right side guide mechanism has set firmly, the integrative conical head that is equipped with of guiding mechanism other end, the inside activity of guiding mechanism be equipped with coupling mechanism, coupling mechanism inside encircle an organic whole and be equipped with anti-skidding stripe.

Furthermore, the guide mechanism consists of a guide pin and a groove.

Furthermore, a guide pin is fixedly arranged on the right side of the outer wall of the handle and is integrally connected with the conical head.

Furthermore, a groove is integrally formed in the guide pin.

Furthermore, the connecting mechanism consists of a cutting knife, a handle, a dovetail groove and a cutting edge.

Further, a cutting knife is movably arranged in the groove, and a handle is fixedly arranged at the top of the cutting knife.

Furthermore, a dovetail groove is integrally formed in one end of the inside of the incision knife, and a cutting edge is integrally formed in the dovetail groove.

Compared with the prior art, this a protected incision knife apparatus for wrist joint syndrome laxation ligament is used, small in size has ensured medical personnel and has treated the definition of the field of vision observation at position to the patient in operation process, and in addition, the device global design in this application is for little incision operation, and is less to the patient damage, can not be because of the too big scar that causes of the open wound of hand.

Drawings

FIG. 1 is a front cross-sectional view of a protective incision tool for use in loosening ligaments for wrist syndrome;

FIG. 2 is an enlarged view of a portion of the cutting knife;

fig. 3 is a perspective view of a protective incision tool for use in loosening ligaments for wrist syndrome.

The cutting tool comprises a handle 1, a guide mechanism 2, a conical head 3, a connecting mechanism 4, an anti-skid stripe 6, a guide pin 7, a groove 8, a cutting knife 9, a handle 10, a dovetail groove 11 and a blade 12.

The following detailed description will be further described in conjunction with the above-identified drawings.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art, that the described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail.

As shown in fig. 1, 2 and 3, the protective incision knife tool for ligament release of wrist joint syndrome comprises a handle 1, a guide mechanism 2, a conical head 3, a connecting mechanism 4 and an anti-slip stripe 6, wherein the guide mechanism 2 is fixedly arranged on the right side of the outer wall of the handle 1, the conical head 3 is integrally arranged at the other end of the guide mechanism 2, the connecting mechanism 4 is movably arranged in the guide mechanism 2, the anti-slip stripe 6 is integrally arranged in the connecting mechanism 4, the guide mechanism 2 consists of a guide pin 7 and a groove 8, the guide pin 7 is fixedly arranged on the right side of the outer wall of the handle 1, the guide pin 7 is integrally connected with the conical head 3, the groove 8 is integrally arranged in the guide pin 7, the connecting mechanism 4 consists of an incision knife 9, a handle 10, a dovetail groove 11 and a knife edge 12, the incision knife 9 is movably arranged in the groove 8, the top of the incision knife 9 is fixedly provided with a handle 10, one end inside the incision knife 9 is integrally provided with a dovetail groove 11, and the inside of the dovetail groove 11 is integrally provided with a blade 12.

This a protected incision sword apparatus for wrist joint syndrome laxation ligament is used, during the use, medical personnel hold the handle 1 with the hand and send into required lax ligament below in the patient treatment position with uide pin 7 and conical head 3, keep off other nerves in the below of uide pin 7 with this, medical personnel hold handle 5 again, will cut the incision sword 9 and slowly get into along the recess 8 of uide pin 7, until cut 9 behind the head position that pushes away uide pin 7 of incision sword, with this completion that realizes the ligament and loosen, the characteristics of device lie in this application: incision sword 9 is the design of

dovetail

11, and 11 internal designs of dovetail have a cutting edge 12, and the outside is glossy surface, can not injure other nerves or tissue after making it get into the tissue, and 7 internal designs of uide pin are the recess 8 shape, can make incision sword 9 pass through smoothly, and small in size can not influence the operation field of vision moreover, and the whole design is little incision operation, and is less to patient's damage, can not be because of the too big scar that causes of open wound of hand.
