Detailed Description
To more clearly illustrate the above objects, features and advantages of the present invention, a detailed description of the embodiments of the present invention is provided in this section in conjunction with the accompanying drawings. As the present invention may be embodied in several forms other than the embodiments described in this section, those skilled in the art should appreciate that they may readily use the present invention as a basis for modifying or modifying other embodiments of the present invention without departing from the spirit or scope of the present invention. The protection scope of the present invention should be subject to the claims.
As shown in fig. 1 and 2, the present invention provides a medical pressure plate apparatus comprising a pressure plate 1 and a sensor, and an electric processing device (not shown). The pressing plate 1 includes a pressing section 12 and a holding section 13, the pressing section 12 is formed in a plate shape and is pressed against the human tissue through a plate surface, and has a pressing end which is in pressing contact with the human tissue. The gripping section 13 is used for an operator (such as a doctor or a gripping tool) to grip or fix at a predetermined position, and may have various patterns and shapes, and the pressing section 12 performs a specific pressing operation by being driven by the gripping section 13. The holding section 13 is not in direct contact with human tissue, and one side of the holding section 13 facing the human tissue is defined as the inner side of the pressing plate 1, and one side of the holding section 13 departing from the human tissue is defined as the outer side of the pressing plate 1.
The sensor is set to measure the deformation and/or force at the preset position of the pressing section 12, the electric processing device can receive the measurement data of the sensor and obtain the pressure applied to the human body by the pressing end of the pressing section 12 through calculation, and the electric processing device also displays the calculation result, namely the pressure applied to the human body by the pressing end, for the reference of doctors.
In this way, the doctor has quantitative recognition of the pressure applied to the human tissue by the pressing plate 1, and can conveniently control the force applied by the pressing plate 1 by observing the numerical value of the force displayed by the electric processing equipment so as to obtain a desired operation effect.
With further reference to fig. 1 and 2, in order to be able to easily measure the magnitude of the deformation or force applied at a predetermined position, the present invention also provides a deformation section which can help the predetermined position of the pressing section 12 to easily obtain a significant deformation.
The deformation section is connected between the pressing section 12 and the holding section 13, and the deformation section may be formed in an arch shape having opposite ends to which the pressing section 12 and the holding section 13 are respectively connected, and a predetermined position is provided at one end where the pressing section 12 and the deformation section are connected.
The pressing section 12 may be formed in a straight plate shape and extend in a tangential direction of one end of an arch formed by the deforming section, and the holding section 13 may also be formed in a straight plate shape and extend in a tangential direction perpendicular to the other end of the arch. It can be seen that the pressing plate 1 is formed overall in a substantially L-shape, the pressing section 12 and the gripping section 13 forming the two branches of the L-shape respectively, and the bending section 14 forming the bent part of the L-shape.
When the pressing end of the pressing part exerts pressure on human tissues, the pressing end is firstly stressed and deformed, other positions on the pressing section 12 are further stressed and deformed, and the arched opening formed by the bent section 14 provides a larger deformation space for the pressing section 12 so as to further relieve the rigidity of the pressing section 12 on the side far away from the pressing end, so that the pressing section 12 can be deformed more easily, and the sensor can more sensitively capture the deformation amount and the stress amount at the preset position.
The generally L-shaped pressure plate 1 creates a larger space between the pressing section 12 and the gripping section 13, which also facilitates efficient use of the small space during clinical procedures.
In order to more easily obtain the deformation at the predetermined position of the pressing section 12, the thickness of the bending section 14 may also be set thinner than the adjacent pressing section 12 and the holding section 13. In this way, not only can a certain connection strength be ensured, but also deformation of the bent section 14 can be promoted.
Specifically, the present invention provides two embodiments having the above technical solutions and capable of obtaining the above technical effects, and further, as shown in fig. 1, in the first embodiment, the sensor may be a strain sensor 2; in a second embodiment, as shown in fig. 2, the sensor may be a force sensor. The differences between the two embodiments are described in detail below.
First embodiment
In this embodiment, the sensor may be a strain sensor 2, and the strain sensor 2 is installed at a predetermined position and directly used for measuring the magnitude of deformation at the predetermined position. When the pressing end applies pressure to human tissues, the pressing end deforms under the stress, the preset position also deforms under the stress and is measured by the strain sensor 2, the strain sensor 2 transmits the measured data to the electric processing equipment, a preset calculation program is stored in the electric processing equipment, and the stress of the pressing end can be converted according to the calculation program and the measured data of the strain sensor 2.
Second embodiment
In this embodiment, the sensor may be a force sensor that is not directly mounted at the predetermined location, but indirectly measures the amount of force applied at the predetermined location.
The medical compression plate device includes a force sensor, a cord 32 and a screw fine adjustment mechanism 3. The force sensor and the screw fine tuning mechanism 3 are packaged as a measuring module which is mounted on the operatively outer side of the grip section 13 (i.e. the side remote from the body tissue). The spiral fine adjustment mechanism 3 is a device capable of rotating to release or recover the rope 32, and the specific structure thereof is common in the prior art and is not described herein. A through hole is formed at one end of the holding section 13 connected with the deformation section, one end of the rope 32 is fixed at a preset position, the other end of the rope passes through the through hole to be connected with the force sensor, and the rope 32 is connected with the spiral fine adjustment mechanism 3 to be capable of being released or recovered under the control of the spiral fine adjustment mechanism 3.
The rope 32 is installed on the pressing plate 1 with tension, the force sensor measures the tension of the rope 32, so that the stress at the preset position is reflected, the measured data is transmitted to the electric processing device, a preset calculation program is stored in the electric processing device, and the stress of the pressing end can be converted according to the calculation program and the measured data of the force sensor.
In addition, in the process of releasing or recovering the rope 32 by using the spiral fine adjustment mechanism 3, a small deformation occurs at a preset position, and the tension of the rope 32 is changed slightly, the force sensor measures the small change of the force and transmits the force to the electric processing equipment, and a doctor accurately adjusts the releasing and recovering of the rope 32 according to the indication of the electric processing equipment, so that the pressing effect of the pressing plate 1 is accurately controlled.
The screw fine adjustment mechanism 3 further comprises a screw mechanism and a fine adjustment knob 31, the screw mechanism and the force sensor are packaged into a measurement module, and the fine adjustment knob 31 is exposed outside the measurement module for a doctor to turn, so that the doctor can control the release and the recovery of the rope 32 more conveniently.
Referring to fig. 1 and 2, taking the perspective of the figures as an example, the human tissue is located at the lower side of the drawing near the pressing end, and the lower side of the holding section 13 is closer to the human tissue than the upper side, so the above-mentioned operation inner side is the lower part of the holding section 13 in the figures, and the operation inner side is the upper part in the figures. The rope 32 is connected to the screw fine adjustment mechanism 3 at the operation outer side of the holding section 13 through the through opening of the holding section 13, which is convenient for the doctor to operate the rope 32.
The medical pressure plate device provided by the invention has the advantages of small volume, high measurement precision and low cost, is suitable for being applied in a narrow space, and is also suitable for being applied under a larger pressing force. In addition, in the embodiment with the screw fine adjustment mechanism 3, the force adjustment is convenient, and the device is more suitable for high-precision application occasions.
The medical pressure plate device provided by the invention is described in detail above, and the following points need to be described:
1. the gripping section may be formed in other shapes and patterns, such as a bar, an arc, etc., but should have a dimension in one direction that is much larger than the other two directions, so as to form a shape extending in the one direction.
2. Other connection modes can be arranged between the holding section and the pressing section as well as the deformation section, for example, the extension direction of the holding section and the tangential direction of the other end of the bending section form an acute angle and an obtuse angle, the extension direction of the pressing section deviates from the tangential direction of one end of the bending section, and the like, and different connection modes are adopted to enable pre-positioning to obtain deformation effects of different degrees under the condition that the pressing ends receive the same pressure.
3. The bending section 14 may also be made of a different material or manufactured by a different process from the adjacent pressing section 12 and the holding section 13, as long as a certain connection strength is ensured and deformation of the bending section 14 is promoted.
4. The invention is not limited by the form of the fine adjustment mechanism, for example, the fine adjustment mechanism can be a screw fine adjustment mechanism, and can also be other linear fine adjustment mechanisms, as long as fine adjustment energy supply can be realized, and the screw fine adjustment mechanism not only can obtain more accurate adjustment effect, but also has lower cost compared with other fine adjustment mechanisms.
5. The ropes may also be fixed by other means, such as welding, etc.
The above embodiments may be arbitrarily combined within a range not departing from the spirit of the present invention. For the sake of brevity, some parts are omitted from the description, however, it should be understood that the parts can be implemented by the prior art.
