Description
Technical Field
The utility model belongs to the field of medical skin opening equipment, and relates to a skin incision device matched with a puncture needle.
Background
Puncture drainage is widely used clinically, and comprises percutaneous nephroscope operation, puncture drainage of kidney and liver cyst, puncture drainage of pus cavity and the like.
The operation of the current clinical ascending puncture drainage generally comprises the following steps: 1. after the puncture is successful, a guide wire is placed through the puncture needle; 2. keeping the puncture needle in the original position and simultaneously performing skin incision; 3. withdrawing the puncture needle, and expanding the puncture channel along the guide wire; 4. after the operation is finished, the drainage tube is placed through the puncture channel after the expansion.
The currently clinically adopted skin incision mode is to directly use a blade to cut the puncture needle up and down. However, in practice, it is relatively difficult to cut the blade through the skin all the way because of the presence of the piercing needle. The main reasons are as follows: 1. because of the puncture needle, the skin can be incised only twice. The blade needs to bypass the puncture needle, so a layer of skin sheet is easily formed between the incision and the puncture hole, and the subsequent expansion is difficult; 2. the incision size of the skin is only based on the experience of the operator, and the quantitative index is lacked. The patient is objectively injured too much (the skin incision is too large), or the skin incision is too small, and the patient needs to be incised again, which affects the operation. There is a need for a simple, quantitative, easy to operate, safe skin cutter for use with a puncture needle.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a skin incision ware of cooperation pjncture needle for solve above-mentioned skin incision ware can not once accomplish the skin cutting, to the big problem of patient's damage.
In order to achieve the purpose, the utility model provides a skin of cooperation pjncture needle opens ware, including cover cavity sleeve pipe, from the top down fixed mounting handle and two cutting edges on the sleeve pipe in proper order outside the pjncture needle, the lower extreme of two cutting edges is 90, equal fixed mounting has the dead lever between the upper end of every cutting edge and the sleeve pipe outer wall, be provided with the scale on the sleeve pipe outer wall.
The beneficial effect of this basic scheme lies in: the hollow sleeve is sleeved outside the puncture needle after puncture, when the puncture needle punctures skin successfully and needs to cut the skin, a doctor holds the handle to push the sleeve with the blade downwards to cut the skin on two sides of the puncture needle to a required size, and the graduated scale on the outer wall of the sleeve is convenient for the doctor to observe and calculate the size of the cut caliber of the skin.
Furthermore, a limiting table is fixedly arranged on the sleeve between the fixed rod and the handle. Has the advantages that: the limiting table prevents doctors from neglecting, and the diameter of the cut skin of a patient is too large due to the fact that the sleeve is pressed too much.
Further, an arc surface is connected between the two cutting edges. Has the advantages that: the arc surface plays a role in slowly opening the incision, so that doctors can conveniently observe and measure the size of the incision, and meanwhile, the injury to intradermal tissues of patients is small.
Furthermore, an anti-slip sleeve is fixedly arranged on the outer side of the handle. Has the advantages that: the anti-slip sleeve plays a role in preventing the patient from being injured by finger slipping in the operation process of the doctor.
Further, the distance between two cutting edge upper ends is 10mm, and the distance between handle and the sleeve pipe top is 5mm, and the handle is cylindricly, and handle length is 10 mm.
Further, the distance between two cutting edge upper ends is 10mm, and the distance between handle and the sleeve pipe top is 5mm, and the handle is discoid, and the handle diameter is 10 mm.
Further, the diameter of spacing platform is 15 mm.
The beneficial effects of the utility model reside in that:
the utility model discloses a skin of cooperation pjncture needle opens ware, with the cover pipe box in this skin opens ware on the pjncture needle after the puncture, the doctor only needs to press down the sleeve pipe of pressing the belt cutting edge, just can open near pjncture needle skin, and the scale that the doctor can observe on the sleeve pipe calculates the incision size, and then the degree of depth that the skin was deepened to the control cutting edge, satisfy the demand of different patient skin opening width, the peripheral incision cutting of whole pjncture needle, just once can accomplish, the trouble of cutting patient's skin many times has been saved, the harm to patient's skin has also been reduced.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.
