Description

Suture extractor

Technical field

The utility model belongs to technical field of medical equipment, is specifically a kind of suture extractor.

Background technology

Otch is to drain blood in medical procedure, commonly using drainage tube, layer-by-layer suture after tripping in drainage tube, still Because the suture number of plies is numerous and sewing needle number is numerous, often there is the situation that muscle and drainage tube are sewed, the so after surgery the 2nd It can not pulled out when it or the 3rd day extraction drainage tube.

The method that we clinically commonly use at present is exactly to take a small scissors to draw cutting suture inside along drainage tube Line, if but the position of suture is deeper, then can not cut, operating room can only be gone successively to cut wound find suture from new, Cut layer-by-layer suture wound again after line.

The content of the invention

The utility model in order to solve the problems, such as drainage tube suture line clipping, there is provided one kind suture extractor.

In order to solve the above technical problems, the utility model takes following technical scheme：One kind suture extractor, including spiral Shape spring, cutter head and bending deformed sleeve pipe, coil spring are inserted in drainage tube, and the external diameter of coil spring is less than etc. In the internal diameter of drainage tube, cutter head and sleeve pipe connection, the internal diameter of sleeve pipe are more than or equal to the external diameter of drainage tube, and cutter head includes some knives Piece, some blades surround circle, and circular internal diameter is more than or equal to the external diameter of drainage tube, and blade front end is circular arc, and blade is upper and lower Both sides have blade.

Described, sleeve pipe includes joint, bellows and net tube layer, and net tube layer is arranged on inner side, net tube layer outside Bellows is provided with, the end of bellows is provided with joint, and joint is connected with cutter head.

Preferably, cutter head is provided with six valve blades.

Preferably, coil spring external diameter is less than the internal diameter 1-2mm of drainage tube.

Preferably, the internal diameter of sleeve pipe is more than the external diameter 1mm of drainage tube.

Preferably, some blades surround external diameter 1-2mm of the internal diameter more than drainage tube of circle.

Above-mentioned technical proposal of the present utility model has the beneficial effect that：

In such scheme, with the coil spring of No.1 smaller than drainage tube, in drainage mouth of pipe insertion drainage tube Portion, against the elasticity of spring itself and stretching property so that drainage tube bends and folded and greatly reduces, and can keep near linear state Under.Six valve cutter heads are connected to bending deformed sleeve pipe below, the valve of cutter head six of use, before be stubbed circular arc, Upper and lower side is sharp blade.The circular arc that such design is intended to the front end when cutter head is packed on drainage tube is not damaged Musculature, drainage tube will not be also damaged, drainage tube will not be cut off.But the suture for sewing drainage tube can take advantage of a situation into six valves In groove between cutter head, there is sharp blade here, as long as rotary cutter, it is possible to suture is cut off, thus may be used To take out drainage tube, drainage tube is not destroyed.

Embodiment

To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing And specific embodiment is described in detail.

One kind suture extractor, including coil spring 2, cutter head 3 and bending deformed sleeve pipe 4, coil spring 2 are inserted Enter in drainage tube 1, the external diameter of coil spring 2 is less than or equal to the internal diameter of drainage tube 1, and cutter head 3 is connected with sleeve pipe 4, sleeve pipe 4 Internal diameter is more than or equal to the external diameter of drainage tube 1, and cutter head 3 includes some blades 3.2, and some blades 3.2 surround circle, circular internal diameter More than or equal to the external diameter of drainage tube 1, the front end of blade 3.2 is circular arc, and the upper and lower both sides of blade have blade 3.1.

As shown in figure 5, sleeve pipe 4 includes joint 4.1, bellows 4.2 and net tube layer 4.3, net tube layer 4.3 is arranged on interior Side, the outside of net tube layer 4.3 are provided with bellows 4.2, and the end of bellows 4.2 is provided with joint 4.1, and joint 4.1 connects with cutter head 3 Connect.

Cutter head 3 is provided with six valve blades 3.2.

The external diameter of coil spring 2 is less than the internal diameter 1-2mm of drainage tube 1.

The internal diameter of sleeve pipe 4 is more than the external diameter 1mm of drainage tube 1.

Some blades 3.2 surround external diameter 1-2mm of the internal diameter more than drainage tube 1 of circle.

As shown in Figure 1：Suture, which sews drainage tube, a variety of situations about sewing, and has the situation for sewing one layer of pipe, sews The situation of two layers of pipe is passed, the situation for having suture to entangle drainage tube, there is the situation for only sewing individual layer drainage tube skin.Drainage tube is in group It is not straight in knitting, sometimes when people organizes intramuscular existing for bending even folding.

As shown in Figure 2：With the coil spring of No.1 smaller than drainage tube, in drainage mouth of pipe insertion drainage tube Portion, against the elasticity of spring itself and stretching property so that drainage tube bends and folded and greatly reduces, and can keep near linear state Under.

As shown in Figure 3：Six valve cutter heads are connected to bending deformed sleeve pipe below（Tubing below is similar to the branch of desk lamp Frame can be with flexural deformation, but also some strength）, my valve of cutter head six, before be stubbed circular arc, in groove under Half part is sharp blade.The circular arc that such design is intended to the front end when cutter head is packed on drainage tube does not damage flesh Meat tissue, drainage tube will not be also damaged, drainage tube will not be cut off.But the suture for sewing drainage tube can take advantage of a situation into six valve knives In groove between head, there is sharp blade here, as long as rotary cutter, it is possible to suture is cut off, thus can be with Drainage tube is taken out, does not destroy drainage tube.

As shown in Figure 4：Enter after packing into drainage tube along inward, run into stop, rotary cutter, it is possible to cut off suture Line.

Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement The scope of protection of the utility model is also should be regarded as with retouching.
