Abstract

The utility model relates to a medical science instructional device especially relates to one kind and can carry out the supersound guide training model of prostate puncture down, goes up to the flat navel of waist, and down to 13 lower departments on the thigh, the model has an anus has rectum, bladder and prostate in, the rectum is connected to the anus, and the bladder lower part is hugged closely to the prostate. The beneficial effects of the utility model are that, enabling the make full use of of faculty and students model, improving the quality of teaching and the puncture level, it can accurately to master this fast, different figures can be simulated to the puncture model, and the image is lifelike, and the teacher can operate the teaching with the model, and the student can contact supersound guide per rectum prostate puncture operation down, can reach the effect of true training and exercise, training model muscle is made by different supersound conductivity's silica gel material with each tissue, can demonstrate different ultrasonograms on the screen when the simulation puncture.

Description

TRUS prostate guided puncturing pattern

Technical field

The utility model relates to a kind of medical teaching utensil, particularly relates to a kind of training pattern of carrying out ultrasound guidance prostate biopsy.

Background technology

Aspiration biopsy of prostatic gland is the most important means of preoperative diagnosis prostate cancer, and option of prostate biopsy guided by transrectal ultrasound is biopsy method the most frequently used at present, because ultrasonic examination can find that intratumoral vasculature increases, blood flow increases.But this have wound inspection method to cause multiple complications, therefore medical personnel are when carrying out the operation of ultrasound guidance per rectum prostate biopsy, requirement is skilled in technique, action is accurate, but the study of per rectum prostate biopsy is long for period, be difficult to grasp in the short time, have inconvenience in the exercise of patient's height more.

Utility model content

The purpose of this utility model is to provide a kind of TRUS prostate guided puncturing pattern, to solve the problem that medical personnel in prior art are difficult to repetition training.

For reaching above object, provide a kind of TRUS prostate guided puncturing pattern, on to the flat navel of waist, down to thigh 1/3 place, described model has anus, inside has rectum, bladder and prostate; Anus connects rectum, the adjacent prostate of bladder.

Preferably, described model is be lithotomy position, or described model is lateral position.Two kinds of model figures commonly use figure when being puncture.

Preferably, described bladder connects urethra, and urethra is through prostate.

Preferably, simulation cavity is had in described rectum, bladder.

Preferably, water filling in described bladder.

Preferably, the muscle of model, bladder, rectum and prostate adopt different silica gel materials to make respectively.

The structure of TRUS prostate guided puncturing pattern simulation human body of the present utility model, comprise essential organs prostate, anus during prostate biopsy, also comprise the organ bladder easily producing wrong puncture position and rectum simultaneously, whether Ultrasound Instrument is stretched into by the anus of model, model exercise point of puncture can be borrowed correct.

The beneficial effects of the utility model are, during energy, classroom and student make full use of model, and improve the quality of teaching and puncture level, grasping this rapidly and accurately can; Puncturing pattern can simulate different figure, lifelike image, and operation teaching can be carried out with model in classroom, and student can contact the operation of ultrasound-guided percutaneous renal fibroblast, can reach the effect of true training and exercise; Training pattern muscle and each tissue are made up of the silica gel material of different ultrasonic conducting performance, when simulating puncture, screen can demonstrate different positions.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

Embodiment 1:

A kind of TRUS prostate guided puncturing pattern according to Fig. 1,2, on to the flat navel of waist, down to thigh 1/3 place, model becomes lithotomy position, and described model entirety is made up of silica gel, above has anus 1, described anus 1 is duct, anus 1 connects rectum 2, and have simulation cavity and mucous membrane in rectum 2, the mucous membrane surrounding rectum 2 is made up of other silica gel being different from model ontology.Be provided with bladder 3 near rectum 2, described bladder 3 is also provided with simulation cavity, has utricule outward, and bladder 3 connects urethra, and urethra is connected to outside through prostate 4.Be marked with water in bladder 3, mistake can there are flowing out when being punctured with.

Embodiment 2:

A kind of TRUS prostate guided puncturing pattern according to Fig. 1,3, all the other are with embodiment 1, and the position of described model is lateral position.

Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
