Technical Field

The utility model relates to a medical instrument, in particular to a lesion size measuring device for an endoscope.

Background

The endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics and software into a whole. One has an image sensor, optical lens, light source illumination, mechanical device, etc. that can enter the stomach orally or through other natural orifices. Since a lesion which cannot be displayed by X-ray can be seen by an endoscope, it is very useful for a doctor. However, the existing endoscope does not have the function of accurately measuring the size of a lesion, so that medical staff cannot carry out reasonable arrangement of treatment means according to the size of the lesion.

SUMMERY OF THE UTILITY MODEL

In view of the above-described disadvantages, an object of the present invention is to provide a lesion size measuring device for an endoscope capable of accurately measuring the size of a lesion.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

a lesion size measuring device for an endoscope comprises a flexible pipe sleeve, wherein the pipe sleeve is provided with a first end and a second end, the first end is coaxially connected with an adjusting sleeve, the inner wall of the adjusting sleeve is annularly provided with a thread, the adjusting sleeve is also provided with a sliding chute parallel to the thread, a stud matched with the thread is arranged in the adjusting sleeve, the side wall of the stud is radially provided with a poke rod penetrating through the sliding chute, and the end face, facing the second end, of the stud is coaxially connected with a transmission shaft; a guide wire is also arranged in the pipe sleeve in a sliding manner, one end of the guide wire is coaxial and rotatably connected with the transmission shaft, a measuring scale is arranged on the end surface of the other end of the guide wire, the measuring scale is connected with the guide wire in a turnover manner, and a graduated scale extending along the length direction of the measuring scale is arranged on the measuring scale; still set up the guide ring on the inside wall of second end, the sliding fit of dipperstick passes the guide ring.

Further, the dipperstick is cylindrical, and the scale ring is located the dipperstick surface.

Furthermore, one end of the measuring ruler, which is far away from the guide wire, is smooth and hemispherical.

Furthermore, the outer side end of the poke rod is connected with a poke block.

Furthermore, have a plurality of discernment color lumps that set gradually along dipperstick length direction on the dipperstick, discernment color lump and each measuring interval one-to-one on the scale.

Further, one end of the measuring scale, which is far away from the guide wire, is provided with a limiting convex ring which can prevent the measuring scale from exiting the guide ring.

Further, the outer portion of the second end is hooped with a reinforcement ring, and the reinforcement ring is arranged flush with the outer surface of the pipe sleeve.

The working principle is as follows: when the size measurement is carried out to patient's pathological change department as required, the staff will this practicality insert to the pincers pipeline of endoscope and go forward to focus department from this, and the staff makes the poker rod slide in the spout through stirring the poker rod afterwards, and along with the slip of poker rod, the double-screw bolt takes place to rotate, and then axial displacement in the control tube, along with the axial displacement of double-screw bolt, the connecting rod of being connected with the double-screw bolt also takes place to remove thereupon, and the connecting rod orders about the seal wire rather than rotatable coupling immediately and axial displacement in the pipe box. And along with the removal of seal wire, the dipperstick that sets up at seal wire tip is pushed out the pipe box by the seal wire, and at the in-process that the dipperstick was pushed out the pipeline, because the restraint of guide ring, the dipperstick outwards takes place the upset. When the poker rod slides the spout and is closest to the position of first end, the dipperstick expandes to target in place, and medical personnel can make the dipperstick remove to pathological change department through operating the endoscope this moment to observe the pathological change department size and size that the dipperstick measured through the observation lens on the endoscope, it needs to explain that, in the measurement process, medical personnel can realize the rotation of dipperstick through twisting the swivel casing, and then carry out the accurate measurement to the length and width of patient's pathological change department.

Has the advantages that: through the structure, the endoscope can accurately measure the size of the lesion of the patient.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A lesion size measuring device for an endoscope as shown in fig. 1 and 2 includes a sleeve 100 made of a flexible material and having a first end 110 and a second end 120. The first end is coaxially connected with an adjusting sleeve 200 made of hard material, the inner wall of the adjusting sleeve is provided with a screw thread 210 in a threaded manner, and the adjusting sleeve is provided with a sliding groove 220 parallel to the screw thread. Meanwhile, a stud 300 matched with the thread in the adjusting sleeve is arranged in the adjusting sleeve, and a poke rod 310 penetrating out of the adjusting sleeve through the sliding groove is radially arranged on the side wall of the stud. The end face of the stud towards the second end is connected with a transmission shaft 320 which is coaxial with the stud, one end of the transmission shaft is connected with a guide wire 400 which is in sliding fit and is inserted in the pipe sleeve, and one end of the guide wire is coaxially and rotatably connected with the transmission shaft. The other end of the guide wire is provided with a measuring scale 500 which is made of hard material and can be connected with the guide wire in a turnover way. It should be noted that the measuring ruler and the guide wire may be hinged or connected by a rubber material with a certain toughness. The measuring scale is provided with a scale 510 extending in the longitudinal direction of the measuring scale. Finally, the angle of upset at every turn is certain when making the dipperstick ejecting to guarantee that the length numerical value that the scale on the dipperstick measured is accurate, be provided with the male guide ring 600 that can supply dipperstick sliding fit on the inner wall of second end, when the dipperstick is stretching out the pipe box in-process, the dipperstick is because receive the guide ring restraint and rotation angle grow gradually, finally realizes the upset of dipperstick and expandes.
