Abstract

The utility model relates to a three-dimensional stereo peritoneoscope which comprises a puncturing tube and an optical fiber puncturing rod which is arranged in the puncturing tube, wherein the optical fiber puncturing rod is a double-optical fiber puncturing rod; two optical fiber heads of the inserting end of the optical fiber puncturing rod have elastic biforked structures; the two optical fiber heads are respectively provided with a taking lens, and the focus points of the taking lenses are consistent. The peritoneoscope has the advantages of scientific design and reasonable structure. The clinical application of the peritoneoscope in an operation can make an operator accurately judge the operation position. When the peritoneoscope is matched with a pair of double-screen liquid crystal display television glasses, because the pair of double-screen liquid crystal display television glasses are worn in front of the operator's eyes, the operator's head and neck can freely move, the operator's visual angle is improved greatly, and the optical degree of comfort is increased.

Description

3 dimension stereo laparoscopes

The utility model relates to medical apparatus and instruments, especially a kind of 3 dimension stereo laparoscopes that are used for observing in abdominal cavity and the thoracic cavity.

At present, the interior observation of the body apparatus that is used for medical field is a kind of two-dimentional peritoneoscope, so-called two-dimentional peritoneoscope is exactly a kind ofly can insert intravital single-lens peritoneoscope by organ, this peritoneoscope is by puncture tube and the optical fiber puncture rod that sets within it, and be installed in the puncture pick-up lens of excellent insertion end of optical fiber and form, optical fiber puncture rod is with after display is connected accordingly, can observe the optical fiber picture that excellent insertion end pick-up lens taken in that punctures by display.Medical field is used the undergo surgery observation of a part in the process of this peritoneoscope, and this can improve the accuracy of operation technique undoubtedly.But the two-dimensional picture that it is found that existing single-lens peritoneoscope in actual applications and reflected does not have distance perspective, can't see the spatial degree of depth.The sign that the operator of operation can only reach on the operating theater instruments by rule of thumb estimates distance, therefore, causes the inaccurate of surgery location easily.

The purpose of this utility model is the deficiency that exists at above-mentioned peritoneoscope, and a kind of 3 dimension stereo laparoscopes are provided.This peritoneoscope can make the operator judge surgery location more accurately.

3 dimension stereo laparoscopes of the present utility model, comprise: puncture tube and the optical fiber puncture rod that sets within it in mode movingly, and be installed in the puncture pick-up lens of excellent insertion end of optical fiber, it is characterized in that: described optical fiber puncture rod is two optical fiber puncture rods, be to be provided with two independently optical fiber in the optical fiber puncture rod, puncture two optical fiber heads of excellent insertion end of optical fiber are the elasticity bifurcation structure, and the pick-up lens of focus point unanimity is housed respectively on two optical fiber heads.

The design principle of this utility model 3 dimension stereo laparoscopes is: the three-dimensional film technology is applied to peritoneoscope, mode with two same focus points of pick-up lens is taken, picture that camera lens is taken the photograph is connected on the corresponding display by optic fibre wire, can obtain the relief picture of tool.If this utility model peritoneoscope is connected with double screen liquid crystal display television glasses, then can make right and left eyes observe corresponding display screen separately, reach and human eye actual observation 3 dimension pictures much at one, its stereoscopic visual effect can be better.

The overall diameter of this utility model 3 dimension stereo laparoscopes is identical with common peritoneoscope, and when the turnover abdominal cavity, the insertion end of optical fiber puncture rod is in puncture tube, and two pick-up lenss inwardly are 40 degree angles, are in closed condition; After puncture tube enters the working area, the optical fiber excellent insertion end that punctures is stretched out in puncture tube, optical fiber behind the disengaging puncture tube punctures excellent insertion end two bifurcation fiber heads under the effect of elastic component, automatic V-shaped shape launches, cold light source is penetrated by optical fiber, the irradiation working area, pick-up lens on the optical fiber head is started working at this moment, two pick-up lenss are represented two eyes of two operators respectively, the screen transition that two pick-up lenss will be taken the photograph becomes the output of telecommunication signal, need the same with existing like product of this peritoneoscope be used with display, and described display can be console display, also double screen glasses.

3 dimension stereo laparoscope design sciences of the present utility model, rational in infrastructure, it can make the operator accurately judge surgery location in operation application clinically; If be used with double screen liquid crystal display television glasses, because double screen liquid crystal display television glasses are worn before operator's eyes, so operator's head, cervical region can be free movable, improved operator's visual angle greatly, improved the comfort level with eye.

The concrete structure of this utility model 3 dimension stereo laparoscopes is provided in detail by the following drawings and embodiment.

Fig. 1 is the structural representation of 3 dimension stereo laparoscopes;

Fig. 2 is 3 dimension stereo laparoscope A-A position profile figure shown in Figure 1;

Fig. 3 is 3 dimension stereo laparoscope B-B position profile figure shown in Figure 1.

Embodiment: can be clear that from Fig. 1,3 dimension stereo laparoscopes are by puncture tube 1 and the optical fiber puncture rod 2 that sets within it, and be installed in the puncture pick-up lens 3 of excellent 2 insertion ends of optical fiber and form, described optical fiber puncture rod 2 is two optical fiber puncture rods (seeing Fig. 2, Fig. 3), be provided with two independently optical fiber 4,5 in the optical fiber puncture rod 2, the front portion of two optical fiber is furnished with metal lead ring 6, for key guiding 7 cooperates, can not misplace between metal lead ring and the optical fiber puncture rod 2 to guarantee the optical fiber excellent 2 two built-in optical fiber 4,5 that puncture.Puncture two optical fiber end 8,9 of excellent 2 insertion ends of optical fiber are bifurcation structure, and it can be identical with 8,9 focus points that pick-up lens 3,11, two pick-up lenss 3,11 are housed respectively of its V-shaped unfolded elastic component 10, two optical fiber end that 8,9 at two bifurcation fiber ends are provided with; The tail end of optical fiber puncture rod 2 is provided with and supplies and the convenient connection-peg 12 that is connected of display.
