Description

Technical Field

[0001] The utility model belongs to the field of medical auxiliary instruments, and in particular relates to an auxiliary ruler for sleeve layout in laparoscopic radical prostatectomy. Background Art

[0002] Prostate cancer (PCa) has the characteristics of slow development, long course and low mortality, which brings a heavy medical burden to the patient's family and society. There are many treatment methods for prostate cancer, including watchful waiting, active monitoring, radical radiotherapy, endocrine therapy and radical prostatectomy (RP). RP is the first choice for localized prostate cancer and the cornerstone of combined treatment for patients with local advanced stage. Since the first report of robot-assisted laparoscopic prostatectomy (RALP) in 2000, robotic laparoscopic technology has gradually become popular in urology. RALP has gradually become the mainstream surgical procedure for organ-confined prostate cancer due to its safety and definite surgical effect.

[0003] The smooth implementation of laparoscopic radical prostatectomy is inseparable from a reasonable cannula layout. Through summarizing past experience and referring to relevant literature, the standardized method of cannula layout design that has been proposed has been widely implemented. However, the specific implementation of this cannula layout is limited by the doctor's experience, the irregular placement of the ruler, and the potential migration during drilling, and errors often occur. Since the robot's arm located outside the body is large, if the cannula layout is too compact, the robot arms are prone to collision, the instrument operation space is small, and the instruments are prone to mutual obstruction and collision during operation, thereby hindering the operation; if the cannula layout is too high, the instrument cannot reach the surgical area due to its fixed length, and the surgical operation cannot be performed. Therefore, if the preoperative auxiliary hole position is not designed reasonably, it will increase the difficulty of operation and affect the progress of the operation.

[0004] Therefore, there is an urgent need for a simplified, rationalized and practical cannula layout perforation auxiliary device to shorten the preoperative preparation time, assist the surgical process, and enable beginners to learn and master the operation in a short time.

[0058] Functions and Effects of the Embodiments

[0059] According to the embodiment, a laparoscopic radical prostatectomy sleeve layout auxiliary ruler is provided, which includes: a first auxiliary part, including a first main board, which is an inverted triangular plate-shaped structure with the top angle facing downward; a second auxiliary part, including a second main board, which is an inverted triangular plate-shaped structure with the top angle facing downward, the bottom angles of the triangular plate-shaped structures of the second main board and the first main board are connected to each other and the bottom edges of the triangular plate-shaped structures are parallel to each other, the planes where the two are located are parallel to each other and the projections of the two planes are axially symmetrical; a lens point is set at the connection between the first main board and the second main board; a first mechanical arm point and a second mechanical arm point are respectively set on the first main board and the top corner of the second main board; the third robotic arm point is set at the bottom corner of the second main board that is not connected to the first main board; the first auxiliary hole point is set at the bottom corner of the first main board that is not connected to the second main board; and the second auxiliary hole point is set on the first main board and is located between the first auxiliary hole point and the lens point, wherein the lens point is used for determining the position of the lens on the umbilicus, the first robotic arm point, the second robotic arm point and the third robotic arm point are used to indicate the position of the robotic arm entering the patient's abdominal cavity through drilling, and the first auxiliary hole point and the second auxiliary hole point are used to indicate the auxiliary position of drilling on the patient's abdominal cavity.

[0060] Therefore, the laparoscopic radical prostatectomy sleeve layout auxiliary ruler of this embodiment can indicate the location of the laparoscopic drilling through different fixed points pre-set on the first main board and the second main board, thereby simplifying the distance measurement steps between the points, and avoiding the problem of position bias that often occurs when marking the upper and lower points on the abdomen, reducing the possibility of errors. It can make it easier for clinicians to clearly understand the positional relationship between the holes that need to be drilled, so as to perform the subsequent drilling operation.

[0061] Furthermore, the triangular plate-shaped structures of the first main board and the second main board are both isosceles triangles, with a base length of 14 cm and a height of 7 cm. The second auxiliary hole point is set on the first main board and is located at the center of the base length of the first main board. Thus, the range between the hole positions indicated by the auxiliary ruler of the laparoscopic radical prostatectomy sleeve layout is determined.

[0062] Furthermore, the laparoscopic radical prostatectomy sleeve layout auxiliary ruler also includes: a connecting portion, including a hinge or a bearing, and the bottom angles of the respective triangular plate-shaped structures of the second main board and the first main board are rotatably connected through the connecting portion. This arrangement makes the laparoscopic radical prostatectomy sleeve layout auxiliary ruler easy to store.

[0063] Furthermore, the second main board and the first main board are in the same plane during the relative rotation process. With this arrangement, when the laparoscopic radical prostatectomy sleeve layout auxiliary ruler is used, it is placed on the patient's abdominal cavity, and the two main boards are level, so as to facilitate indicating the drilling position.

[0064] Furthermore, the laparoscopic radical prostatectomy sleeve layout auxiliary ruler also includes: a positioning part, including: a fixing piece, which is arranged at the bottom corner of the first main board and is located beside the connecting part; and a matching piece, which is arranged at the bottom corner of the second main board and is located beside the connecting part, wherein the matching piece and the fixing piece are matched and detachably abutted, so that the first main board and the second main board are positioned when the first main board and the second main board are in a "W" shape as a whole during relative rotation and the straight lines where their respective bottom edges coincide. The fixing part is a protrusion arranged at the bottom corner of the first main board and located beside the connecting part, and the protrusion does not exceed the range of the plane where the first main board is located. The matching part includes: a longitudinal protrusion, which is arranged at the bottom corner of the second main board and located beside the connecting part along the vertical direction of the plane where the second main board is located, and the longitudinal protrusion does not exceed the range of the plane where the second main board is located, and the direction in which the longitudinal protrusion is arranged is coplanar with the fixing part, and a lateral protrusion, which is arranged on the longitudinal protrusion in a lateral extension. When the first main board and the second main board are in a "W" shape as a whole during the relative rotation process and the straight lines where their respective bottom edges are located coincide, the lateral protrusion extends in the direction of the first main board and abuts against the fixing part. Such a setting enables the auxiliary ruler for the layout of the sleeve of laparoscopic radical prostatectomy to be fixed when the whole is in a "W" shape, so that it is not easy to produce deviations due to excessive relative rotation of the two main boards during auxiliary drilling.

[0065] Furthermore, the plane of the triangular plate-shaped structure of the first main board and / or the second main board is penetrated with a through groove for the operator to hold and operate the laparoscopic radical prostatectomy sleeve layout auxiliary ruler, and the bottom edge of the triangular plate-shaped structure of the first main board and / or the second main board is provided with a scale, and the scale setting method includes a smear mark, a protrusion or a groove. Such a setting enables the auxiliary ruler to indicate a specific distance and is easy to hold.

[0066] Furthermore, the thickness of the first main board and / or the second main board is 0.1 cm, the edges and corners of the first main board and / or the second main board are rounded to avoid scratching or irritating the skin of the operator and / or the patient, and the material of the first main board and / or the second main board includes any one or more of wood, metal, PVC or hard skin-friendly silicone. Such a configuration makes the auxiliary ruler suitable for being placed directly on the patient's abdominal cavity without causing adverse effects.
