The specific embodiment
Disclosed all features in this description, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this description (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, a kind of operation supporting sleeve of use capable of being combined and puncture guiding needle, the main body of sleeve pipe 1 is the pipe that has perforate 2 on the tube wall, the head of puncture guiding needle 4 is pointed, when being used in combination (in the guiding puncture process), sleeve pipe 1 is sleeved on the afterbody of puncture guiding needle 4 both one integrated mass that combines.After sleeve pipe 1 is sleeved on the afterbody of puncture guiding needle, the front end of sleeve pipe 1 is positioned at the step place of puncture guiding needle 4, and (the big end of the head 3 of puncture guiding needle 4 end face diameters are greater than afterbody 3 body diameters, promptly formed step), there is aileron 5 its rear end, the outside diameter that is enclosed within the sleeve pipe 1 on the puncture guiding needle 4 is slightly less than or is slightly larger than or equal the head 3 big end end face diameters of puncture guiding needle 4, when puncture guiding needle 4 is introduced surgery location with sleeve pipe 1 (guiding puncture finish after), sleeve pipe 1 from the portion of puncture guiding needle 4 from, puncture guiding needle 4 takes out from skin incision.The afterbody of puncture guiding needle 4 passes whole sleeve pipe 1, the afterbody of puncture guiding needle 4 passes whole sleeve pipe 1 back exposing at sleeve pipe 1 has one to transfix thorn guide needle 4 afterbodys for a short time, puncture guiding needle 4 cylindrical tail portion of exposing sleeve pipe 1 outside by the 5 usefulness hand push of the aileron on the operation supporting sleeve, make puncture guiding needle pass from skin incision quick separation of realizing sleeve pipe 1 and puncture guiding needle 4, and sleeve pipe 1 is trapped in operative site.
As Fig. 1, Fig. 2 and Fig. 3, shown in Figure 4, the main body of sleeve pipe 1 is the pipe that has perforate 2 on the tube wall, the main body of sleeve pipe 1 is that pipe is convenient to be complementary for cylindrical with the afterbody 6 of puncture guiding needle 4, and perforate 2 can be designed to rectangle or ellipse, and perforate 2 is to be convenient to perform the operation plastic cutter and other instrumentation; One end of sleeve pipe 1 has aileron 5, and the shape of aileron 5 can be designed to ellipse or circle or rectangle.The material of this supporting sleeve 1 need be convenient to the detailed observation operative site ambient conditions of doctor, and it is indeformable and make things convenient for the doctor to carry out operations such as ligament cut-out that its structural requirement can stand the extruding of operative site.According to above-mentioned requirements, sleeve pipe 1 can be selected that transparency is good, hardness is high, is convenient to sterilization, the material of no toxicity, as polypropylene etc.
As shown in Figure 5 and Figure 6, the head 3 of puncture guiding needle 4 is straight-tapered or curved taper, promptly can be made into taper, bent angle type, asymmetric taper, flat bent angle shape etc., can select the puncture guiding needle 4 of straight-tapered or curved taper for use according to the different parts that the nerve card weighs operation wounded, be convenient to puncture, expansion and guiding; Head is that the puncture guiding needle 4 of straight-tapered or curved taper can be used in combination with supporting sleeve 1, and the afterbody 6 of puncture guiding needle 4 is cylindrical, is convenient to be used in combination with supporting sleeve 1; The head 3 big end end face diameters of puncture guiding needle 4 are greater than afterbody 6 body diameters, purpose is at puncture guiding needle 4 afterbody suit supporting sleeves, after putting sleeve pipe, the outside diameter of supporting sleeve is slightly less than or is slightly larger than or equal the big end end face diameter of head of puncture guiding needle, is convenient to so successfully supporting sleeve 1 be introduced operative site by puncture guiding needle 4 in piercing process.This puncture guiding needle 4 requires hardness height, intensity height, is convenient to sterilization, no toxicity, so can select for use medical PVC or materials such as PP or medical stainless steel to make.
As Fig. 7, Fig. 8 and shown in Figure 9, the main body of this operation billhook 7 is flat taper, and its head 8 is bent into semi-annular shape backward; Sharp and use dexterously for the blade of the billhook that guarantees to perform the operation, blade 9 basils of this operation billhook are designed to 8 °～30 °.With the body design of this operation billhook is flat taper, its head 8 is designed to recurvate semi-annular shape, exactly in order to guarantee to perform the operation in use flexibly light and handy of billhook and be convenient to be allowed to condition at motion in the elongated perforate 2 on the supporting sleeve 1, to cut off the corresponding ligament of operative site quickly and accurately.After adopting the operation billhook of this structure, carry out nerve and block when weighing the ligament amputation wounded, convenient to use, and can cut off corresponding ligament exactly and protect operative site perienchyma to greatest extent, improve the safety of operation.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and shown in Figure 9, when the nerve card that carries out wrist or other positions weighs the ligament resection operation wounded, need earlier sleeve pipe 1 to be sleeved on the afterbody of puncture guiding needle 4, head with puncture guiding needle 4 penetrates from the near-end skin incision then, this moment, puncture guiding needle 4 and sleeve pipe 1 inserted in the lump, through puncture guide needle 4 sleeve pipe 1 is introduced surgery location, when arriving the operation correct position, afterbody with hand push puncture guiding needle 4, simultaneously the aileron 5 of sleeve pipe 1 is held, this moment, puncture guiding needle 4 passed from the far-end skin incisions, sleeve pipe 1 is trapped in operative site, again endoscope is put into sleeve pipe 1 to observe the situation of operative site by the transparent wall of sleeve pipe 1 after adjusting the position of sleeve pipe 1, the billhook 7 of will performing the operation at last stretches in the sleeve pipe 1, when confirming that billhook 7 walks to tough band distal end edge, blade upwards lifted by the perforate on the sleeve pipe 12 catch on tough band distal end edge to near-end tractive and cutting, ligament is promptly cut off.Perforate 2 design on the sleeve pipe 1 is exactly to cut off ligament for the ease of operation billhook 7 by perforate 2, and the size of perforate 2 is complementary with the size of operation plastic cutter, like this safety and conveniently more during cutting operation; Aileron 5 designs on the sleeve pipe 1 are separating for the ease of puncture guiding needle 4 and sleeve pipe 1, when taking out puncture guiding needle 4, sleeve pipe 1 can not take out thereupon, make sleeve pipe 1 be trapped in operative site, and can make things convenient for the adjustment of sleeve pipe 1 position, help the doctor in operation the perforate on the locating sleeve 12 over against direction.
This utility model is not limited to the aforesaid specific embodiment.This utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
