Abstract
A simulation teaching model for local surgery mainly comprises a human body simulation pelvis model and a pedestal. The human body simulation pelvis model comprises bones, nerves, ligaments, muscles, an obturator membrane, a rectum, blood vessels, a vagina and an ischial spine, the bones are made of PVC plastics, the other parts are all made of zero silica gel, the silica gel on the exterior of the pelvis model is not transparent, and the interior silica gel of the pelvis model is transparent. The simulation teaching model for the local surgery is provided with lifelike profile and real hand feeling, and it is convenient for users to repeatedly exercise.
Description
Technical field
The utility model relates to a kind of teaching appliance, relates in particular to a kind of local operation silica gel realistic model that can be used for teaching and training use.
Background technology
In some clinical operation, doctor need to carry out specified tissue, specify the operation technique between internal organs under the condition of the non-visual field, under conventional conditions, be all after operative doctor relies in range estimation comparison, art inside and outside feeler inspection patient the anatomical features of local organization organ and locates with this, could determine direction and the position of concrete operations.In visible art, the accuracy height of puncture procedure relies on the know well degree of operative doctor to this topography structure, otherwise neural blood vessel or organ all likely come to harm and threat to life.Emulation silica gel model just in time allows doctor under the condition of emulation, impression and practise various operations, until be familiar with, help the 3 D stereo anatomic image of setting up in brain, yet to operate and just can drive a light carriage on a familiar road on human body in the future., in the market, as the model of this type of training, just utilize three-dimensional environment in computer simulation body or only with the plastics built-up pattern that can not practise operating to doctor's observational learning, be to allow doctor have the operation of the sense of reality like this.
Utility model content
The purpose of this utility model is: a kind of body local realistic model of doing repeated puncture operation for doctor is provided, is beneficial to the operation technique exercise of carrying out under the condition of the various non-visuals field, so that familiar with anatomy position and operation.
The utility model is achieved in that a kind of local operation Emulational teaching model, mainly by human emulation pelvis model and base, formed, human emulation pelvis model comprises bone, nerve, ligament, muscle, fat, skin, obturator membrane, rectum, blood vessel, vagina and ischial spine, described bone adopts PVC plastics to make, all the other are all made with zero degree silica gel, the silica gel of described pelvis model outside is not penetrating, and inner silica gel is penetrating.
Preferably, described base and pelvis model are for removably connecting.
Preferably, the silica gel of different parts can be dyed different colors.
The utility model has the advantages that:
1, emulation feel.When its soft durometer is zero degree, material is similar with human connective tissue, can simulate and comprise skin, subcutaneous fat, muscle, blood vessel, nerve, the body tissue such as enteron aisle and internal organs, and the emulation silica gel model that can imitate different tissues and organ color and luster producer soma and organ is for surgical simulation training;
2, emulation changes.When zero degree silica gel is not more than 4mm in puncture aperture, reinstatement voluntarily, the body changing condition during puncture of closing to reality tissue;
3, adopt the zero degree silica gel material that can restore voluntarily to make, model can repeat exercise and use, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: nervus pudendus 1, ischial spine 2, ligamentum sacrospinosum 3, ligamentum sacrotuberosum 4, obturator membrane 5, introitus 6, obturator nerve and branch 7 thereof, rectum 8, upper closed pore film spot OS, lower closed pore film spot OI, ligamentum sacrospinosum point SSL.
Embodiment
As shown in Figure 1, the utility model mainly consists of human emulation pelvis model and base, it is characterized in that: human emulation pelvis model comprises bone, nerve, ligament, muscle, obturator membrane, rectum, blood vessel, vagina and ischial spine, described bone adopts PVC plastics to make, all the other are all made with zero degree silica gel, and wrap PVC bone, and the silica gel of described pelvis model outside is not penetrating, and inner silica gel is penetrating.When a people is front, do puncture exercise; And another people is when rear, can know the puncture situation of seeing pelvis inside, whether correct to supervise point of puncture and process.
Zero degree silica gel described in the utility model has emulation feel, and hardness is similar to skin, fat, and muscle, blood vessel and nerve, internal organs, so puncture therein has and true similar sensation; Another silica gel can be dyed different colors, so, also there is color and intend true sense. when this practises doctor, can see the mistake of operation. also have, the various organ shape in model can be moulded;
When zero degree silica gel is not more than 4mm in puncture aperture, reinstatement voluntarily, the body changing condition during puncture of closing to reality tissue; And adopting the zero degree silica gel material that can restore voluntarily to make, model can repeat exercise and use.
As shown in Figure 1, when model being carried out to sticking patch prolapsus repairing and/or urinary incontinence sling surgery, doctor need to enter vagina front and rear wall place by outside puncture, and just because of the above-mentioned simulated properties of zero degree silica gel, thereby make doctor accurately by upper closed pore film spot OS, penetrate under urethra or anterior vaginal wall place by repeating to realize, by lower closed pore film spot OI, penetrate into anterior vaginal wall fornix place, enter pelvic cavity arrival posterior vaginal wall fornix place after simultaneously penetrating and pass ligamentum sacrospinosum point SSL by buttocks.
The silica gel that obturator membrane place is used is replaceable structure, is beneficial to when using too much or damaging and substitutes.
Because in actual operation, three site OS that puncture is passed through, OI, SSL must be correct, if OS and OI puncture are incorrect, very likely damage obturator nerve, make pain and larger harm, and when arriving anterior vaginal wall, also likely damage bladder, and if SSL puncture is incorrect, may damage nervus pudendus, rectum, even large blood vessel.
The application of human emulation pelvis model, can carry out as the operation as true operation doctor, by the method touching, is familiar with the points for attention of operation, thereby grasps this operation.
The utility model can also be made the multiple model such as stomach wall model, wall of the chest model and practise for intern.
Above structure of the present utility model is set forth, but the embodiment that the utility model is introduced in this not conditional intention, within not deviating from the scope of the utility model purport, the utility model can have multiple variation and modification.
