Abstract

The utility model relates to an analogue discipline device for basic operation of surgery. The device forms a simulative soft tissue three-layer compound structure through two monolayer fabrics in different colors and a fiber layer of an intermediate sandwich. The imitative stomach and intestinal canal model provided with the utility model can provide a real teaching tool for the hemostasis, suture, vascular anastomosis and organ anastomosis after cutting in basic operations of student training, which plays a fairly important role in disciplining a surgical student to grow into a skilled surgeon from a novice.

Description

Operation basic operation analog training device

Technical field

The utility model belongs to a kind of medical science simulation teaching aid.Specifically, it is to belong to the analogue means that propaedeutics is used in the operation, especially for hemostasis after the tissue dissection the most basic in the training operation and stitching training.

Background technology

Surgical basic training is to cut, stop blooding, sew up, and this also is three big critical operations of operation success or failure.Yet only teach from books, even is good again, it is ripe again that operation technique and standard are carried on the back, and without tempering of practice, also is difficult to successfully finish for the first time practical operation.Without practice, or even repeatedly underproof failure experience, real surgeon shows one's talent never, grows up.So, attach great importance to training in the surgery teaching to young student's practical operation.In wall chart teaching, clinically view and emulate, outside the film, television teaching, also carry out the animal simulated training at all costs.So that allow the sensation of student's firsthand experience execute-in-place, experience the various hints on operations of taking action on one's own.Zoopery becomes the perform the operation main means of ability of student of cultivating.Though effect is pretty good, technical sophistication, the testing expenses height so the real chance that participates in of student is very few, can't be accomplished the requirement of basic skills on top of far away.Add and have no the chance and the psychological preparation of being in the action in advance, only " animal " operation testing machine is the carrying out of " in a rush " also often, the result who has no to keep forging ahead and waste substantial contribution.Chance as for human body (corpse mark) is then rare more, only has one or two people to have a chance or opportunity, so for the surgical clinical doctor, the basic operation of its operation can only be waited for and go in the working opportunity slowly to cultivate.It is very unfavorable that this must strengthen surgeon's ability of performing the operation.How to allow in the clinic student learn basic operation in the operation skill, gimmick, be puzzled student and teacher's big problem always.

Summary of the invention

The purpose of this utility model provides a kind of operation basic operation analog training device, directly applies to the training of operation technique initial stage.Be by practiced repeatedly personally in simulation soft tissue, intestinal tube, Weishang " hemostasis ", " stitching " basic gimmick and normalization procedure step the classmate, and skillfully it, beat next solid operation basis and cultivate psychological quality for entering " animal experiment " or bedside practice.

Basic design concept of the present utility model is a three-layer combined structure of forming a simulation human body soft tissue with flexible fabric or fibrage.Be made into the bag shape of imitative stomach and the elongated tubular of imitative intestinal tube again, and form distinct level sensation.In the three-layer combined structure of analogue body organ soft tissue, represent the inner chamber mucous layer with red woven, the outer individual layer white fabrics of using is represented organ appearance placenta percreta, and the centre is by multiply cloth or has certain thickness fiber composite layer to represent smooth muscle.When operation stitching, respective layer knot suture quality obviously can be distinguished, and checks out the skill and technique and the effect of its stitching like this.

Description of drawings

Fig. 1 is simulation " stomach " synoptic diagram.

Fig. 2 is simulation " intestinal tube " synoptic diagram.

Fig. 3 coincide for " stomach ", " intestines of sewing up in the training synoptic diagram ".

Fig. 4 is " intestines " pipe side-to-side anastomosis training synoptic diagram.

Wherein, 1 is simulation " stomach ", and 1A is the gastric mucosa layer, and 1B is a smooth muscle layer, and 1C is the ectoplasm rete, and 2 are simulation " intestinal tube ", and 3 is blutpunkte (redness), and 4 is the artery and vein ends of vessels of cutting off, and 2 A are " intestinal tube " lateral incision.

What Fig. 3 provided is that the student training stomach is cut the synoptic diagram that the back stomach and intestine are sewed up entirely.Fig. 4 represents the diagram after analogue means can carry out the identical operation training in intestinal tube side.Can also allow the student practise the stitching in the various clinical operation, the overall process of stopping blooding operation, comprise little tubule ligation " 8 " word penetrating ligature, the corresponding stitching of intracutaneous gimmick, " 8 " word are sewed up, " stomach " otch dwindles the identical operation of butt joint " intestinal tube ".The side is sewed up between intestines, and the blood vessel butt joint coincide and waits complicated technical ability.

Embodiment

The simulation bag shape device 1 that the simulation soft tissue of three-layer combined structure can be sewn into imitative stomach shape during concrete enforcement is called simulation " stomach ".Wherein inner chamber gastric mucosa layer 1A adopts red woven to constitute, and outside surface is white woven, represents stomach appearance placenta percreta 1C.The centre is that cellucotton is represented smooth muscle layer 1B.There is punctation to represent blutpunkte 3 on the outside surface.Fig. 2 is " intestinal tube " analogue means that provides, and it is oval tubulose.Artery and vein blood vessel broken end 4 after being furnished with blutpunkte 3 above and cutting off.In order to train the sew application in the side anastomosis on intestinal tube 2 models, to be provided with side otch 2A.Training for convenience, " stomach " and " intestinal tube " of simulation all can be made into the upper and lower opening shape, and the artery and vein blood vessel with the small hose simulation breaks end 4 on organ, sews up procedural training in order to the standard of doing vascular anastomosis training and various anastomosis operations.

Surgery is specialized in the student and is learnt on textbook after various basic stitchings, the hemostasis operation skill and technique, learn again and understand in the various operations sew up skill and standard after, just can get corresponding analogue means, finish hemostasis, stitching operation according to teacher ' s guidance.The subject of its training can comprise nearly ten seeds training such as gastrointestinal anastomosis, blood vessel termination, side intestinal surface coincide.And an analogue means can repeatedly be used repeatedly, until the student on top of and till reaching certain skill level.At this moment, go up the student of animal experiment or bedside practice again, just be different from the student who not have to pass through this training process significantly, its psychological quality and success ratio and the degree of reliability of finishing clinical operation first improve greatly.Because its training cost is low, effect is remarkable, and is widely applicable, becomes the welcome of cultivating the indispensable educational aid of surgeon and will be subjected to medical colleges and schools and hospital's vocational education in the future.
