Description

Skin incision device matched with puncture needle

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.

Example 1

As shown in figure 1, the skin incision device matched with the puncture needle comprises a hollow sleeve 1 sleeved outside the puncture needle, a handle 2 fixedly installed on the sleeve 1 from top to bottom and two blades 3, wherein an anti-skid sleeve is fixedly installed on the outer side of the handle 2. The anti-slip sleeve plays a role in preventing the patient from being injured by finger slipping in the operation process of the doctor. The lower extreme of two cutting edges 3 is 90, and equal fixed mounting has dead lever 4 between the upper end of every cutting edge 3 and the sleeve pipe 1 outer wall, is provided with scale 6 on the sleeve pipe 1 outer wall. The distance between 3 upper ends of two cutting edges is 10mm, and the distance between 2 and the sleeve pipe 1 top is 5mm, and handle 2 is cylindricly, and 2 lengths of handle are 10 mm.

When the skin incision device matched with the puncture needle is used, the hollow sleeve 1 is firstly sleeved outside the puncture needle after puncture, when the puncture needle punctures skin successfully and needs to be incised, a doctor holds the handle 2 to push the sleeve 1 provided with the blade 3 downwards, then the diameter of the drainage tube is inserted according to needs to incise the skin on two sides of the puncture needle to the needed size, and the graduated scale 6 on the outer wall of the sleeve 1 is convenient for the doctor to observe and calculate the size of the cut caliber of the skin.

Example 2

As shown in fig. 2, embodiment 2 of the skin incision device for fitting a puncture needle differs from embodiment 1 in that a disk-shaped stopper 5 is fixedly mounted on a cannula 1 between a fixing lever 4 and a handle 2, and the diameter of the stopper 5 is 15mm in the skin incision device disclosed in embodiment 2. The limiting table 5 prevents doctors from neglecting, and the diameter of the cut skin of the patient is too large due to the fact that the sleeve 1 is pressed too hard.

Example 3

Example 3 is different from example 1 in that the distance between the upper ends of two blades 3 in the skin incision device disclosed in example 3 is 10mm, the distance between the handle 2 and the uppermost end of the cannula 1 is 5mm, the handle 2 has a disk shape, and the diameter of the handle 2 is 10 mm.
